Refactor capability checks in Client:_supports_registration and
Client:supports_method to properly handle dynamicRegistration and unknown
methods. Now, dynamic capabilities are checked before assuming support for
unknown methods, ensuring more accurate LSP feature detection.
Problem:
`vim.system()` doesn't invoke a shell, while the Vimscript function
`system()` does.
Solution:
Revert the change from 35af766de6 and use `vim.fn.system()` again to
actually invoke a shell.
Problem:
The builtin terminfo defs don't include xterm-ghostty, so features like
`kTerm_set_underline_style` are missing when building without unibilium.
Solution:
- Add ghostty to `gen_terminfo.lua`.
- Note: The ncurses defs are somewhat different than what ghostty ships.
- Special-case ghostty in `terminfo_from_builtin`.
Problem:
If the last visible line in a window is not fully displayed, this line
may not get injection highlighting. This happens because line('w$')
actually means the last *completely displayed* line.
Solution:
Use line('w$') + 1 for the botline.

"test: fix failing lsp/utils_spec #36609",
which changed the test based on the wrong behavior.
Problem:
When using the Nvim appimage, `~/.cache/nvim/luac` directory can grow to
250,000+ files.
Example of 2 identical files in `./luac/`:
%2ftmp%2f.mount_nvim.a65Rja0%2fusr%2fshare%2fnvim%2fruntime%2flua%2fvim%2ftreesitter.luac
%2ftmp%2f.mount_nvim.aNpxXgo%2fusr%2fshare%2fnvim%2fruntime%2flua%2fvim%2ftreesitter.luac
Analysis:
The `nvim.appimage` mounts nvim at a different temporary path each time
it is invoked. The naming scheme of these cache files is random, which
defats the purpose of the cache creates N new files on every launch of
nvim.
Steps to reproduce:
1. install `nvim.appimage`
2. `mv ~/.cache/nvim/luac ~/.cache/nvim/luac.backup`
3. `nvim`
4. Observe contents of `~/.cache/nvim/luac/`
5. Close nvim and run `nvim` again
6. Observe contents of `~/.cache/nvim/luac/` and see that new identical
files have been added with a different mount prefix
Solution:
When running from an appimage, trim the random part of the filepaths.
Problem:
After bc0635a9fc `vim.wait()` rejects floats
and NaN values.
Solution:
Restore the prior behavior, while still supporting `math.huge`. Update
tests to cover float case.
Problem:
Current options for powershell and pwsh had mistakes and rationale
behind them was not clear.
Solution:
Update the suggested options by splitting up powershell and pwsh, as
well as ensuring that all options work and rationale is documented and
discussed.
Problem: diff: missing diff size limit for xdiff
Solution: Impose file size limit for internal diff (xdiff)
(Yee Cheng Chin).
Git imposes a hard cap on file size for content that it passes to xdiff
(added to Git in dcd1742e56e, defined in xdiff-interface.h), due to
integer overflow concerns in xdiff. Vim doesn't specify such a limit
right now, which means it's possible for a user to diff a large file
(1GB+) and trigger these overflow issues.
Add the same size limit (1GB minus 1MB) to Vim and simply throws an
error when Vim encounters files larger than said limit. For now, reuse
the same error message regarding internal diff failures. There is no
need to add the same limit for external diff as it's up to each tool to
error check their input to decide what is appropriate or not.

Problem:
The execution of startup scripts in parent directories are too late
compared to scripts in current direcctory.
Solution:
Execute all startup scripts with `lua/_core/exrc.lua`.
closes: #35147
Problem:
`clint.py` is the last python in our codebase, and beyond that it needs
some cleanup. And it lacks tests, so modifying it can be painful.
Also, we need a way to add ad-hoc lint rules for *Lua*, so it will help
to have our ad-hoc rules for C in the same language (the scripts may
share functions/techniques): https://github.com/neovim/neovim/issues/28372
Solution:
- convert to `clint.lua` (mostly AI-generated, but it now has test
coverage, unlike `clint.py`)
- drop rules that are no longer needed:
- "readability/multiline_string"
- technially still relevant, but very uncommon so doesn't really matter.
- "--line-length"
- Not used in the old clint.py, nor the new clint.lua.
- "comment whitespace" check
- It is enforced by uncrustify.
- "TODO" check
- The `-google-readability-function-size` clang-tidy rule enforces
"TODO(user)" format. (It was already enabled long ago.)
Problem:
Our LSP type system didnt have a concept of RegistrationMethods, this is where the method to dynamically register for a capability is sent to a different method endpoint then is used to call it. Eg `textDocument/semanticTokens` rather than the specific full/range/delta methods
Solution:
Extended generator to create `vim.lsp.protocol.Methods.Registration` with these registration methods. Also extend `_request_name_to_client_capability` to cover these methods. Adjust typing to suit
Problem:
Every CI log has a lot of noise at the end, which makes it harder to
find relevant test failures:

Solution:
- Skip logging in test-mode.
- This can be reverted later, when these logs are changed to "INFO"
level, per this TODO comment:
```
// TODO(bfredl): This is really ILOG but we want it in all builds.
// add to show_verbose_terminfo() without being too racy ????
WLOG("TUI: terminal mode %d unavailable, state %d", mode, state);
```
Problem:
If a `vim.lsp.config` explicitly sets `exit_timeout`, that indicates the
config wants that behavior for most usages of `:stop()`.
Solution:
Update `:stop()` to use `force=exit_timeout` if `force` was not
explicitly passed.
Problem: Windows: Vim always adds the current directory to search path.
This should only happen when using cmd.exe as 'shell'. For
example, powershell won't run binaries from the current
directory.
Solution: Only add current directory to system path, when using cmd.exe
as 'shell'.

- cleanup of PR for tearing and other output options
- removed `allow_tearing` from global keywords (it's only an output option)
- moved `...clockwise` directives from general to transform options
- separated `icc` highlight to correctly detect and highlight paths
- updated output bg to use the same approach as `icc` for file path
- separated all identifier-matchers into their own groups
- added support for bar identifiers
