Problem: The matchparen plugin is slow on a long line.
Solution: Don't use a regexp to get char at and before cursor.

Example:
```vim
call setline(1, repeat(' foobar', 100000))
runtime plugin/matchparen.vim

fix(terminal): interrupt/got_int hangs terminal (#30056)
Upon `terminal_enter`, `mapped_ctrl_c` is set in order to avoid `CTRL-C`
interrupts (which is proxied to the terminal process instead), `os_inchar`
will then test `mapped_ctrl_c` against `State` and set `ctrl_c_interrupts=false`
which prevents `process_ctrl_c` from setting `got_int=true` in a terminal
state.
However, if `got_int` is set outside of `process_ctrl_c`, e.g. via
`interrupt()`, this will hang the neovim process as `terminal_execute` will
enter an endless loop as `got_int` will never be cleared causing `safe_vgetc`
to always return `Ctrl_C`.
A minimal example reproducing this bug:
```vim
:autocmd TermEnter * call timer_start(500, {-> interrupt()})
:terminal
:startinsert
```
To fix, we make sure `got_int` is cleared inside `terminal_execute` when
it detects `Ctrl_C`.

`buf.code_action` always included diagnostics on a given line from all

the exact same format they sent it.

Problem: [security] use-after-free in tagstack_clear_entry
(Suyue Guo )
Solution: Instead of manually calling vim_free() on each of the tagstack
entries, let's use tagstack_clear_entry(), which will
also free the stack, but using the VIM_CLEAR macro,
which prevents a use-after-free by setting those pointers
to NULL
This addresses CVE-2024-41957

Problem: Unable to move cursor to recently opened window.
Solution: Make sure uninitialized window is drawn before trying to move
the cursor to it.

Problem: Marks whose position did not change with the action that
invalidated them (right_gravity = false) are not revalidated
upon undo.
Solution: Remove early return when restoring a marks saved position so
that it is still revalidated. Add "move" guards instead.

Problem: Wrong cursor position with 'breakindent' when a double-width
character doesn't fit in a screen line (mikoto2000)
Solution: Include the width of the 'breakindent' properly.

Problem: :TOhtml doesn't properly handle virtual text when it has
multiple highlight groups. It also improperly calculates position offset
for multi-byte virt_text characters.
Solution: Apply the `vim.api.nvim_strwidth` broadly to properly
calculate character offset, and handle the cases where the `hl` argument
can be a table of multiple hl groups.
Problem: Modifying a sign no longer updates already placed signs.
Solution: Loop over (newly-exposed) placed decorations when modifying a
sign definition. Update placed decor if it belongs to the sign
that is modified.

Problem:
When there are multiple inlay hints present at the same position, they
should be rendered in the order they are received in the response from
LSP as per the LSP spec. Currently, this is not respected.
Solution:
Gather all hints for a given position, and then set it in a single
extmark call instead of multiple set_extmark calls. This leads to fewer
extmark calls and correct inlay hints being rendered.
Problem: Neovim bundles treesitter parsers for bash and python but does
not use them by default. This dilutes the messaging about the bundled
parsers being required for functionality or reasonable out-of-the-box
experience. It also increases the risk of query incompatibilities for no
gain.
Solution: Stop bundling bash and python parser and queries.

Problem:
Error when calling vim.treesitter.start() and vim.treesitter.stop() in

Ensure syntaxset augroup exists after loading synload.vim.

Problem: Treesitter highlighter clears the already populated highlight
state when performing spell checking while drawing a
smoothscrolled topline.
Solution: Save and restore the highlight state in the highlighter's
_on_spell_nav callback.

Problem: Hit assert when clicking inside a padded 'statuscolumn' that
is padded beyond the length of the allocated click_defs.
Solution: Still consider this a "in_statuscol" click, but return early
when about to execute the click func.

Problem:
When 'ignorecase' is set, the default keymap Q and Q would exit visual
mode.
This issue was raised in #28287 and a fix was applied in #28289.
However, `==` operator is subject to user `ignorecase` setting.
Solution:
Switching to `==#` operator would guarantee case sensitive comparison
between visual mode and linewise visual mode.

Problem: Legacy :sign API still allows placing signs beyond the end of
the buffer. This is unaccounted for by the signcolumn tracking
logic and is disallowed in general for the extmark API which
implements it now.
Solution: Clamp legacy sign line number to the length of the buffer.

fix(tui): move $COLORTERM check to _defaults.lua (#29197)
We currently check $COLORTERM in the TUI process to determine if the
terminal supports 24 bit color (truecolor). If $COLORTERM is "truecolor"
or "24bit" then we automatically assume that the terminal supports
truecolor, but if $COLORTERM is set to any other value we still query
the terminal.
The `rgb` flag of the UI struct is a boolean which only indicates
whether the UI supports truecolor, but does not have a 3rd state that we
can use to represent "we don't know if the UI supports truecolor". We
currently use `rgb=false` to represent this "we don't know" state, and
we use XTGETTCAP and DECRQSS queries to determine at runtime if the
terminal supports truecolor. However, if $COLORTERM is set to a value
besides "truecolor" or "24bit" (e.g. "256" or "16) that is a clear
indication that the terminal _does not_ support truecolor, so it is
incorrect to treat `rgb=false` as "we don't know" in that case.
Instead, in the TUI process we only check for the terminfo capabilities.
This must be done in the TUI process because we do not have access to
this information in the core Neovim process when `_defaults.lua` runs.
If the TUI cannot determine truecolor support from terminfo alone, we
set `rgb=false` to indicate "we don't know if the terminal supports
truecolor yet, keep checking". When we get to `_defaults.lua`, we can
then check $COLORTERM and only query the terminal if it is unset.
This means that users can explicitly opt out of truecolor determination
by setting `COLORTERM=256` (or similar) in their environment.

Problem: Unsetting global variables earlier in #28578 to avoid
recursiveness, caused superfluous or even unlimited
showmode().
Solution: Partly revert #28578 so that the globals are unset at the end
of showmode(), and avoid recursiveness for ext UI by adding a
recursive function guard to each generated UI call that may
call a Lua callback.
(cherry picked from commit b66106a46c)
Problem: Numberwidth may depend on number of signs with text in the
buffer and is not handled correctly for extmark signs.
Solution: Move legacy sign code for changed numberwidth so that it is
handled properly for legacy and extmark signs alike.

On Windows, '{' is currently not treated as a wildcard char, so another
wildcard char is needed for the pattern to be treated as a wildcard.
It may be worth trying to make '{' always a wildcard char in the future,
but that'll be a bit harder as it'll be necessary to make sure '{' is
escaped at various places.

fix(comment): fall back to using trimmed comment markers (#28938)
Problem: Currently comment detection, addition, and removal are done
by matching 'commentstring' exactly. This has the downside when users
want to add comment markers with space (like with `-- %s`
commentstring) but also be able to uncomment lines that do not contain
space (like `--aaa`).
Solution: Use the following approach:
- Line is commented if it matches 'commentstring' with trimmed parts.
- Adding comment is 100% relying on 'commentstring' parts (as is now).
- Removing comment is first trying exact 'commentstring' parts with
fallback on trying its trimmed parts.
