In most languages, Zed will check 2-3 locations for language servers.
For instance, when opening a python file, zed looks for ruff in:

- project venv
- user's PATH
- location that zed installs language servers

The language server menu surfaces information that makes it easier to
gather data about your language server, I think offering a path for the
one being ran makes things more clear to the user.

That being said, Idk the best way to surface this. (@danilo-leal?)

Release Notes:

- Add language server path to a tooltip that is produced when hovering
on its status in the language server menu

While at it, annotate more functions that are potentially related to
language parsing in buffers.

Also, on macOS, in order to actually have callstack frames properly
recorded by Tracy, you need to manually run `dsymutil` on the binary.

Adds the ability to create a dev container definition from scratch.
Additionally, separates devcontainer logic out into its own crate, since
it was getting sufficiently complex to separate from the
`recent_projects` crate.

Release Notes:

with `projects: initialize dev container`
- Added podman support for dev container actions with the `use_podman`
setting
- Improved devcontainer error handling

Previously, `always_confirm` patterns would force confirmation even when
`always_allow_tool_actions` was set to true. This was counterintuitive
since the global setting should provide a way to skip all confirmations.

The new precedence order is:
1. **`always_deny`** - still blocks for security
2. **`always_allow_tool_actions`** - when true, allows all non-denied
actions
3. **`always_confirm`** - prompts if `always_allow_tool_actions` is
false
4. **`always_allow`** - allows without prompting
5. **`default_mode`** - fallback behavior

This means setting `always_allow_tool_actions=true` will now skip
confirmation prompts from `always_confirm` patterns and override
`default_mode: Deny` settings, while still respecting `always_deny`
patterns for security.

(No release notes because granular tool permissions are still
feature-flagged.)

This PR fixes the fact that we weren't showing any @-mentions (files,
images, etc.) in the queue preview.

Release Notes:

- Agent: FIxed a bug with the message queue in the agent panel where
@-mentions weren't being displayed in the message preview within the
queue entries list.

Follow up to https://github.com/zed-industries/zed/pull/46797

When you send a message, as per the PR linked above, Zed will now queue
it by default. But if you want to fast-track it/interrupt the agent
immediately, effectively sending the first message in the queue, you can
just hit enter again and it will get sent right away.

Release Notes:

- Agent: Made it easier to interrupt the agent while having messages in

When viewing a branch diff (e.g., 'Changes since origin/main'), the
toolbar was hidden because `ProjectDiffToolbar` filters for
`DiffBase::Head` only. This meant users couldn't send review comments to
the Agent panel from the branch diff view.

Now there's a new `BranchDiffToolbar` which:
- Only activates for branch diff views (`DiffBase::Merge`)
- Shows only the 'Send Review to Agent' button (not stage/unstage
controls)
- Only appears when there are review comments (same behavior as the
existing toolbar)

(No release notes because this is still feature-flagged.)

Reproduction steps:

- Zed main branch
- Use Ollama (likely provider agnostic) in the agent panel with the
following prompt: "Explore the codebase with subagents"
- Panic

```
thread 'main' (36268) panicked at C:\Users\username\.cargo\registry\src\index.crates.io-1949cf8c6b5b557f\futures-util-0.3.31\src\stream\unfold.rs:108:21:
Unfold must not be polled after it returned `Poll::Ready(None)`
```

Following the stack trace we get to `Thread::run_turn_internal`. I
believe the panic happens in the following code which was introduced in
#46802

```rust
// Collect all immediately available events to process as a batch
let mut batch = vec![first_event];
while let Some(event) = events.next().now_or_never().flatten() {
    batch.push(event);
}
```

Both `Option`s get flattened, however the inner `Option` represents the
end of the stream, after which polling the stream using `.next()` will
result in a panic.

We could fix the logic in this particular spot, but I believe the
simpler solution is to `.fuse()` the stream, which stops the stream from
panic'ing even after it has ended. This also prevents misuse in the
future.

The panic was introduces on main and did not land on a release yet, so
no release notes.

Fixes an issue where `editor::AddSelectionAbove` and
`editor::AddSelectionBelow`, when set with `skip_soft_wrap: true` ,
would lose track of the original cursor column when passing through
short lines, as `editor::Editor.add_selection` was not using the oldest
selection's column range when adding a new selection.

These changes update the `editor::Editor.add_selection` method so as to
keep track of the olde selection's column range for each group, as well
as extracting `find_next_columnar_selection_by_display_row` and
`find_next_columnar_selection_by_buffer_row` helper methods to clarify
the two navigation strategies.

Closes #46842

Release Notes:

- Fixed `editor::AddSelectionAbove` and `editor::AddSelectionBelow` when
skipping over soft-wrapped lines to preserve the original cursor column
when adding selections through lines shorter than the starting position

Closes #ISSUE

Moves the settings content definitions into their own crate, so that
they are compiled+cached separately from settings, primarily to avoid
recompiles due to changes in gpui. In that vain many gpui types such as
font weight/features, and `SharedString` were replaced in the content
crate, either with `*Content` types for font/modifier things, or
`String`/`Arc<str>` for `SharedString`. To make the conversions easy a
new trait method in the settings crate named `IntoGpui::into_gpui`
allows for `into()` like conversions to the gpui types in
`from_settings` impls.
