Problem: Clearing the screen doesn't clear the "last" virtual text.
Dupe counter virtual text is not increased beyond 1.
Solution: Clear "last" virtual text when clearing the screen.

Add a guarded "C++ 26 extensions" block (cpp_no_cpp26) covering new
lexical surface introduced since C++23:
- [[ ... ]] attributes as a region, so P3394 annotations carrying a
value expression (eg [[=foo{1}]]) no longer trip cErrInBracket on
their braces/parens. A \w\@1<! look-behind keeps it from matching a
subscripted immediately-invoked lambda (arr[[]{...}()]).
- ^^ reflection operator (P2996).
- [: :] splice brackets (P2996).
- contract_assert keyword (P2900).
Add input/cpp_cpp26.cpp exercising these constructs with screendumps,
and update dumps/cpp_noreturn_00.dump for the new [[ ]] attribute
delimiter highlighting.

Problem: Terminal background and truecolor detection runs only at startup,
gated on a UI being attached. A headless server has no UI then, so
`'background'` and `'termguicolors'` are never detected and remote
UIs ignore the terminal's theme.
Solution: Also (re)detect on UIEnter. The most recently attached terminal
wins; an explicit user value is preserved.
Problem: Writing a message with a large number of newlines
(:echo "foo\n"->repeat(1000000)) takes longer than it has to
(since c973c7ae).
Solution: Accumulate newlines in a single API call when possible.
Problem: LspNotify never passed a buffer when executing the autocmds, so
buffer-local LspNotify autocmd subscriptions didn't have the correct buf
in the event metadata. It was also wrapped in a schedule() so the actual
autocmd was delayed until after the event loop.
This could result in the wrong buffer receiving the notification if
multiple LspNotify autocmds with buffer filters were added. Only the
"latest" one would actually receive non-buffer-filtered autocmds, not
the matching one. It also caused listeners to receive the notification
"out of sync" with when the notification is actually sent. If a buffer
is being deleted (which fires a textDocument/didClose notification), the
notification is scheduled and fired after the buffer is already gone.
Solution: For LSP notifications that pertain to a particular buffer, set
it when executing the LspNotify autocmds so the callback functions that
are filtered on that buffer will get the correct notifications and the
metadata buf field will be correct. Additionally, there is no need to
wrap the LspNotify callback in vim.schedule when it can be called inline
when the notification to the rpc server is fired.
This is tested by removing now-unnecessary autocmds from semantic tokens
(InsertEnter and BufWinEnter should no longer be necessary now that
requests are fired by LspNotify). Without this fix, simply modifying a
buffer doesn't actually trigger LspNotify correctly, and the test for
that fails.
Problem: When multiline semantic token support was introduced, the loop
that finds the end line for a particular token didn't sanitize the token
length sent back by the LSP server. If the server returned an overflowed
length (near uint32 max), neovim would burn cpu and loop for an
extremely long time while trying to find the "end line" represented by
the massively large token, causing neovim to seemingly hang.
Solution: Stop looping once the calculated end_line reaches the actual
last line of the buffer.
Fixes#36257
Problem:
- Current 'statuscolumn' click label caveat is restrictive.
- v:virtnum is not unique to a line if it has both above and
below virtual lines.
- 'statuscolumn' click handler may expect v:virt/lnum to be set.
Solution:
- Store per-row click definitions for the statuscolumn in a
(nested line/virt number) map.
- Implement strategy that gives each 'statuscolumn' row a unique
v:virtnum.
- Set v:virt/lnum when determining which line is clicked.
Problem: linked_editing_range was still doing most of the capability
boilerplate itself.
Solution: refactor it to make use of the common Capability framework for
handling enabling, disabling, etc.
Patch 9.2.0306 fixed malformed lz4 extraction commands by using "tar -I lz4"
on Linux and leaving non-Linux tar implementations to auto-detect lz4 input.
That still fails on systems where tar does not support either -I lz4 or
automatic lz4 decompression, such as Solaris /usr/bin/tar.
Keep the existing Linux path using GNU tar's "-I lz4" support. For non-Linux
systems, use lz4 explicitly to decompress the archive to stdout and feed the
resulting tar stream to the configured tar extraction command. This is the
same style tar.vim already used for lz4 archives before patch 9.2.0306.

Problem:
:Man does not syntax highlight codeblocks (injected language).
Analysis:
init_pager() swapped pcall(parse_ref, ref) return values order, so
vim.b.man_sect was set to the manpage name instead of the section
number, so C syntax highlighting did not load.
Solution:
Swap the calls.
Today there is a constraint that these arguments to the enable filter be
mutually exclusive, but I do not know why such a constraint exists (it
is perfectly reasonable to want to enable a capabilility for just one
buffer and just one client).
Problem: [security]: s:NetrwLocalRmFile() escapes only the backslash in
the file name before passing it to :execute, so a name
containing "|" injects arbitrary Ex commands when the file is
deleted (cipher-creator)

This commit makes processing the erlangOperator and erlangBitType syntax
items faster.
- erlangOperator changes:
- Vim now parses erlangOperator faster because we define the operators
individually.
- The order of operators in erlangOperator had to be changed to make
the edge cases work the same as before (for example
erlangEqualsBinary).
- erlangBitType changes:
- Vim now parses erlangBitType faster because:
1. Now the long `\%(integer\|float\|...\)` sections are preceded by
"beginning of word" patterns (`\<`).
2. Now we use the old regexp engine (`\%#=1`).
Previously when an Erlang file contained long lines with erlangOperator
or erlangBitType patterns near the end, redrawing these lines was slow,
and typing at the end of the line was also slow.
For example, redrawing a 1787 characters long test line is now roughly
six times faster.

Problem:
an empty `{ isIncomplete = true, items = {} }` ends completion
instead of requerying.
Solution:
keep isIncomplete on empty lists and retrigger on keypress while incomplete.
Reset on <C-e> so it doesn't immediately re-query.
Problem: a font set via nvim_set_hl is lost or corrupted with font-only groups,
attribute combining, and update=true, and is dropped on any attr-table rebuild.
nvim__inspect_cell also frees the font name while a returned dict still borrows it.
Solution: register font-only groups, carry font through hl_combine_attr, inherit
it on update, and persist sg_font so a rebuild can restore it. Keep interned font
names across a rebuild instead of clearing them. Add the missing font field to
get_hl_info.

Problem: vim.diagnostic.Opts.VirtualLines.current_line and
vim.diagnostic.Opts.VirtualText.current_line cause redraw
on every CursorMoved event that makes the text jump
uncomfortably with rapid cursor movement.
Solution: `current_line` state is applied only on CursorHold,
while still being cleared on CursorMoved making it so that
until the cursor has stopped on a line, its diagnostic
looks like cursor is not on the line preventing flicker.

fix https://github.com/neovim/neovim/issues/40235
Problem: The refactor to use Capability left around some cruft and
semi-broken configuration for debounce.
Solution: Clean up now-unnecessary helper methods and simplify
deprecated ones to pass through to the non-deprecated ones. `debounce`
now defaults to 200 for all buffers but is overridable via the
deprecated start() method, which continues to take the max value
specified for any client attached to the buffer.
If we wish to expose changing the debounce in a non-deprecated way, we
will need to consider a "configuration" function, or even a bespoke
method to set the debounce time on the main metaclass (or provide
options to override for a particular buffer). General configuration of
specific LSP features is an as-of-yet unsolved problem.
Problem:
On some non-US keyboards, like Estonian/Swedish/etc, widely used []
characters in vim are hard to type. One way to overcome this is to use langmap
option to map accented characters, that are in the same place as [] on US
keyboards to []. Unfortunately this does not work currently in neovim, it
cannot map multibyte characters via langmap.
Solution:
The fix iterates over characters in typeahead and key buffers, instead of bytes,
in getchar.c handle_mapping(). It does not handle macros though, these tests are
still failing when turned on.

Problem:
Any random ftplugin or other autocmd, can throw an error when
`:checktime` reloads a buffer. This causes a trace which makes it look
like an issue with `autoread.lua`.

Solution:
Use pcall() and surface the error via nvim_echo.
Problem:
Old 'autoread' only did `:checktime` on focus-change and shell (":!")
commands, and only for non-hidden buffers. Since 'autoread' is now
driven by OS filewatcher events, buffers are updated much more eagerly.
This should be surfaced to the user somehow, either via a carefully
placed notification, or a minimal UI indicator.
A "notification" would be noisy, unless it is conditional on specific
circumstances (e.g. when "many" buffers are updated).
Solution:
Use the existing 'busy' buffer-local option as a subtle hint about
activity.
Problem: The semantic token module is using its own debounce timer for
the buffer on_lines event. If its internal debounce is shorter than the
changetracking module's debounce, it's possible for semantic token
requests to fire for changed buffers before the textDocument/didChange
notification is sent to the server.
Solution: Trigger semantic token requests from the LspNotify autocmd
when the method is the didChange or didOpen notifications, which
enforces a strict happens-before relationship for the sync change
notification followed by a semantic token request.
Note: There is still an internal debounce mechanism in the semantic
token module to handle other debouncing needs specific to its
functionality, such as debouncing server refresh notifications and
handling WinScrolled events when using range requests.
Problem: Keys valid in CTRL-X mode are never mapped while insert
completion is active, so <C-N> and <C-P> cannot be remapped
for completion started by complete().
Solution: Do not disable mappings in CTRL_X_EVAL mode. In this mode a
mapping cannot interfere with selecting the completion
method, which is what the no-mapping rule exists for.

Problem: The "%" command jumps to parens and braces inside comments,
unlike the "=" operator (cindent), which ignores them.
Solution: When 'comments' defines C-style comments and "%" is not in
'cpoptions', skip matching parens inside such comments, except
when the cursor is inside a comment so a match there can still
be found.

Problem: Running `vim.filetype.match()` when current working directory
was removed from disk throws a `vim.fs.abspath` assertion error.
However, the matching might still be possible without trying to match
against full path (like if it is a known extension).
Solution: Safely compute absolute path and ignore it if it errors.
Problem: Diagnostic virtual lines are hardcoded with "scroll" for
virt_lines_overflow option.
Solution: Add a `overflow` option to `virtual_lines` config
to support "wrap", "scroll", "trunc", and "auto".
Problem:
The 'autoread' option only checks for file changes reactively — on
FocusGained, :checktime, CmdlineEnter, etc. — by polling timestamps.
External changes are not detected until the user interacts with Neovim.
Solution:
Add a core module (runtime/lua/nvim/autoread.lua) enabled from
runtime/plugin/autoread.lua that watches each buffer's file using
vim._watch.watch() (libuv fs_event). On change detection it calls
:checktime, which invokes the existing buf_check_timestamp() logic
for reload/prompt handling. Watchers are managed via autocmds tied
to buffer lifecycle events and respect the 'autoread' option (global
and buffer-local).
