With this, scrollbars across the app will now auto-hide unless it is
specified that they should follow a specific setting.

Optimally, we would just track the user preference by default. However,
this is currently not possible. because the setting we would need to
read lives in `editor` and we cannot read that from within the `ui`
crate.

Release Notes:

- N/A

Closes https://github.com/zed-industries/zed/issues/37660

This PR makes sections in the AI settings UI more consistent with each
other and also just overall simpler. One of the main changes here is
adding the tools from a given MCP server in a modal (as opposed to in a
disclosure within the settings view). That's mostly an artifact of
wanting to make all of the items within sections look more of the same.
Then, in the process of doing so, also changed the logic that we were
using to display MCP servers; previously, in the case of extension-based
servers, we were only showing those that were _configured_, which felt
wrong because you should be able to see everything you have _installed_,
despite of its status (configured or not).

However, there's still a bit of a bug (to be solved in a follow-up PR),
which already existed but it was just not visible given we'd only
display configured servers: an MCP server installed through an extension
stays as a "custom server" until it is configured. If you don't
configure it, you can't also uninstall it from the settings view (though
it is possible to do so via the extensions UI).

Release Notes:

- agent: Improve settings view UI and solve issue where MCP servers
would get unsorted upon turning them on and off (they're all
alphabetically sorted now).

Without this, I would never have converged on @cole-miller's patch
https://github.com/zed-industries/zed/pull/38380 when debugging codelldb

The built-up command for the WSL remote connection looks like

```
wsl.exe --distribution Ubuntu --user cole --cd /home/cole -- bash -c SCRIPT
```

Where `SCRIPT` is a command itself. We don't need extra quotes around
`SCRIPT` because we already pass it whole as a separate argument to
`wsl.exe`.

This isn't yet enough to get ACP servers working in WSL projects
(#38332), but it removes one roadblock.

Release Notes:

- windows: Fixed an issue that could prevent running binaries in WSL
remote projects.

Release Notes:

- N/A *or* Added/Fixed/Improved ...

We were incorrectly handling the line number as well as stripping out
line breaks when returning portions of files.

It also makes sure following is updated even when we load a snapshot
from cache, which wasn't the case before.

We also are able to load the text via a range in the snapshot, rather
than allocating a string for the entire file and then another after
iterating over lines in the file.

Release Notes:

- acp: Fix incorrect behavior when ACP agents requested to read portions
of files.

Closes #34192

Without selection, only current character would be affected.

Also if #38117 is merged too, then transformations in SelectMode behave

select modes

Closes #38304 

Release Notes:

- Fixed true color detection regression by setting `COLORTERM=truecolor`

---

Reason:

The regression is possibly introduced in [pr#36576: Inject venv
environment via the
toolchain](https://github.com/zed-industries/zed/pull/36576/files#diff-6f30387876b79f1de44f8193401d6c8fb49a2156479c4f2e32bc922ec5d54d76),
where `alacritty_terminal::tty::setup_env();` is removed.

The `alacritty_terminal::tty::setup_env();` does 2 things, which sets
`TERM` & `COLORTERM` envvar.
```rs
/// Setup environment variables.
pub fn setup_env() {
    // Default to 'alacritty' terminfo if it is available, otherwise
    // default to 'xterm-256color'. May be overridden by user's config
    // below.
    let terminfo = if terminfo_exists("alacritty") { "alacritty" } else { "xterm-256color" };
    unsafe { env::set_var("TERM", terminfo) };

    // Advertise 24-bit color support.
    unsafe { env::set_var("COLORTERM", "truecolor") };
}
```

Tests that the downstream project can see custom agents configured in
the remote server's settings, and that it constructs an appropriate
`AgentServerCommand`.

Release Notes:

- N/A

In local projects, initialize the list of agents in the agent server
store immediately. Previously we were initializing the list only after a
delay, in an attempt to avoid sending the `ExternalAgentsUpdated`
message to the downstream client (if any) before its handlers were
initialized. But we already have a separate codepath for that situation,
in the `AgentServerStore::shared`, and we can insert the delay in that
place instead.

Release Notes:

- acp: Fixed a bug where starting an external agent thread soon after
Zed starts up would show a "not registered" error.

Closes #11760

The command `project panel: collapse all entries` currently does not
collapse top-level entries (the workspaces themselves). I think this
should be expected behaviour if you only have a single workspace in your
project. However, if you have multiple workspaces, we should collapse
their top-level folders as well. This is the expected behaviour in the
screenshots in #11760.

For more context: Atm the `.retain` function empties the
`self.expanded_dir_ids` Hash Map, because the `expanded_entries` Vec is
(almost) never empty - it contains the id of the `root_entry` of the
workspace.


https://github.com/zed-industries/zed/blob/d48d6a745409a8998998ed59c28493a1aa733ebb/crates/project_panel/src/project_panel.rs#L1148-L1152

We then update the `self.expanded_dir_ids` in the
`update_visible_entries` function, and since the Hash Map is empty, we
execute the `hash_map::Entry::Vacant` arm of the following match
statement.


https://github.com/zed-industries/zed/blob/d48d6a745409a8998998ed59c28493a1aa733ebb/crates/project_panel/src/project_panel.rs#L3062-L3073

This change makes sure that we do not clear the `expanded_dir_ids`
HashMap and always keep the keys for all visible workspaces and
therefore we run the `hash_map::Entry::Occupied` arm, which does not
override the `expanded_dir_ids` anymore.

Bug in https://github.com/zed-industries/zed/pull/32927

Instead of using trigger characters to clear cached completions items,
now we check if the query is empty to clear it. Turns out Emmet defines
whole [alphanumeric as trigger
characters](https://github.com/olrtg/emmet-language-server/blob/279be108725fb391c167690b697ce154fd32657b/index.ts#L116)
which causes flickering.

Clear on trigger characters was introduced to get rid of cached
completions like in the case of "Parent.Foo.Bar", where "." is one of
the trigger characters. This works still since "." is not part of
`completion_query_characters` and hence we use it as a boundary while
building the current query. i.e in this case, the query would be empty
after typing ".", clearing cached completions.

Release Notes:

- Fixed issue where completions menu flashed on every keystroke in TSX
files with emmet extension installed.
