One motivation is that the outlines returned by `read_file` for large
files list line numbers assuming an inclusive `end_line`. As a result,
when the agent uses these outlines for `read_line` calls, it would
otherwise miss the last line.

resolves #24655
resolves #23945

I haven't yet added a default binding for the new command. #27797 added `:ls` and
`:buffers` which in my opinion should use the global searchable version
given that that matches the vim semantics of those commands better than
just showing the tabs in the local pane.

There's also a question of what to do when you select a tab from another
pane, should the focus jump to that pane or should that tab move to the
currently focused pane? For now I've implemented the former.

Release Notes:

- Added `tab_switcher::ToggleAll` to search open tabs from all panes and focus the selected one.

Do not insert hard/soft tabs for cursors at the suggested indent level
if any other cursor lies before the suggested indent level. This PR
brings us one step closer to fixing
https://github.com/zed-industries/zed/issues/26157.

Before:


https://github.com/user-attachments/assets/8fd5cde4-99f4-4363-9292-5da8dadab658

After:


https://github.com/user-attachments/assets/17c9f8ca-5842-452b-8665-7c7138d50162

Release Notes:

- Fixed an issue where using tab with multiple cursors would result in
inconsistent relative indentation across lines.

`App::http_client` and `Client::http_client` both return an owned `Arc`
which it clones internally. This means we can remove unnecessary clones
when calling these methods.

Release Notes:

- N/A

These were nearly always used when using `format!` / `write!` etc, so it
makes sense to not have an intermediate `String`.

Release Notes:

- N/A

Add note about manual restart
Remove taplo LSP settings example (broken)

Truncation to a 32 bit `usize` could cause two distinct IDs to be

Closes #29255

Release Notes:

- Improved handling of markdown escape sequences

Closes #29439

Add shell escaping as well as additional sanity check for Zed path when
used in askpass. This caused issues on preview and nightly as the
standard paths for those releases contain spaces which were not escaped
appropriately leading to erroneous "Permission denied" errors from SSH
when the askpass script failed

Release Notes:

- Fixed a missing shell-escape in askpass resulting in erroneous
"Permission denied" errors when trying to connect to a remote server
over ssh (effecting preview release v0.184.1 and nightly only)

Add new test and improve fuzzy match bucket logic which results into far
better balance between LSP and fuzzy search.

Since #28065 merged we've seen deadlocks inside iconv when opening Zed
in a repository containing many submodules. These calls to iconv happen
inside libgit2, in our implementations of the methods `head_sha`,
`merge_head_shas`, and `show` on `RealGitRepository`. This PR moves
those methods to use the git CLI instead, sidestepping the issue. For
the sake of efficiency, a new `revparse_batch` method is added that uses
`git cat-file` to resolve several ref names in one invocation. I
originally intended to make `show` operate in batch mode as well (or
instead), but I can't see a good way to do that with the git CLI; `git
show` always bails on the first ref that it can't resolve, and
`for-each-ref` doesn't support symbolic refs like `HEAD`.

Separately, I removed the calls to `show` in `MergeDetails::load`, going
back to only loading the SHAs of the various merge heads. Loading full
commit details was intended to support the inlays feature that ended up
being cut from #28065, and we can add it back in when we need it.

This PR adds a new `subscription_usage_meters` table to the LLM

This fixes a deadlock that would occur when `DapStore` had its on quit
handler called. The deadlock was caused by `DapStore` spawning on the
main thread while `App::shutdown` blocks the main thread.

We added a debug_panic in GPUI that panics if a foreground task is
spawned while the App context is shutting down. This will help tests
catch hangs in `cx.on_app_quit` calls.

Since around the time we shipped block diagnostics, we've been seeing an
out of range panic in the editor.

Although the code is heavily inlined, so the stacktrace is missing, this
seems like a likely place that indexing may have gone wrong.

Release Notes:

- Fixed a rare panic in the editor

Added `snippet_sort_order`, which determines how snippets are sorted
relative to other completion items. It can have the values `top`,
`bottom`, or `inline`, with `inline` being the default.

This mimics VS Code’s setting:
https://code.visualstudio.com/docs/editing/intellisense#_snippets-in-suggestions

Release Notes:

- Added support for `snippet_sort_order` to control snippet sorting
behavior in code completion menus.

This update generates a single self-contained .html file that shows an
overview of evaluation threads in the browser. It's useful for:

- Quickly reviewing results
- Sharing evaluation runs
- Debugging
- Comparing models (TBD)

Features:

- Export thread JSON from the UI
- Keyboard navigation (j/k or Ctrl + ←/→)
- Toggle between compact and full views

Generating the overview:

- `cargo run -p eval` will write this file in the run dir's root.
- Or you can call `cargo run -p eval --bin explorer` to generate it
without running evals.

Release Notes:

Part of https://github.com/zed-industries/zed/issues/16472

* Adds debug logging to everywhere near INSERT/UPDATEs in the DB

So something like 
`env RUST_LOG=debug,wasmtime_cranelift=off,cranelift_codegen=off,vte=off
cargo run` could be used to view these (current zlog seems to process
the exclusions odd, so not sure this is the optimal RUST_LOG line) can
be used to debug any further writes.

* Removes excessive window stack serialization

Previously, it serialized unconditionally every 100ms.
Now, only if the stack had changed, which is now check every 500ms.

* Removes excessive terminal serialization

Previously, it serialized its `cwd` on every `ItemEvent::UpdateTab`
which was caused by e.g. any character output.
Now, only if the `cwd` has changed at the next event processing time.

Release Notes:

- Fixed more excessive DB writes

Previously, all MCP tools would be completed regardless if they were
disabled/enabled for the profile. This meant that the "Write" profile
was always using all MCP tools, even if you disabled them in the
settings.

Now, when `enable_all_context_servers` is set to `true`, we will enable
all tools from all MCP servers by default but disable the ones that are
explicitly disabled for the profile.

Also fixes an issue where the tools would not show up as enabled when
using `enable_all_context_servers: true`

Release Notes:

- agent: Fix an issue where MCP tools could not be enabled/disabled

This PR removes the `language-models` feature flag.

This feature is already generally available, so we no longer need the
feature flag.
