This PR fixes the generation of summaries for threads when tools are
being used.

Previously we were including the tool uses in the summarization request,
but this would result in invalid messages being sent to the model and
summaries not being generated.

We now exclude any tool uses or results from the model when summarizing
a thread.

Release Notes:

- N/A

This PR makes `auto` an alias for the `subtle` edit prediction mode.

- Closes https://github.com/zed-industries/zed/issues/22818

Usage: `ssh -F ssh_config user@host.tld`

```
-F configfile
    Specifies an alternative per-user configuration file. If a configuration file
    is given on the command line, the system-wide configuration file
    (/etc/ssh/ssh_config) will be ignored. The default for the per-user
    configuration file is ~/.ssh/config. If set to “none”, no configuration files
    will be read.
```

Release Notes:

- ssh: Added support for specifying ssh_config files (`ssh -F
ssh_config`) in connection string

- Closes: https://github.com/zed-industries/zed/issues/22380

Arch linux ships busybox wget not gnu wget.
BusyBox wget does not support `--max-redirect`.

Release Notes:

- Multibuffers: Unfold excerpts when editing their contents.

Co-authored-by: Max Brunsfeld <maxbrunsfeld@gmail.com>

Closes https://github.com/zed-industries/zed/issues/22912

Reworks the task context infrastructure so that it's possible to have
multiple contexts at the same time, and stores all possible worktree
context there.
Task UI code is now falling back to the "active" worktree context, if
active item's context did not produce a resolved task.

Current code does not produce meaningful results for projects with
multiple worktrees to avoid ambiguity and design changes: instead of
resolving tasks per worktree context available, extra worktree context
is only used when resolving tasks from the same worktree.

Release Notes:

- Improved Zed tasks' `ZED_WORKTREE_ROOT` fallbacks

When migrating to gpui2,
https://github.com/zed-industries/zed/commit/588976d27a22bb36a5aac7e762b21e180a66a2f9#diff-a3da3181e4ab4f73aa1697d7b6dc0caa0c17b2a187fb83b076dfc0234ec91f54R21
removed the diagnostic style for "active but invalid" case: presumably,
it served as some sort of a cursor to show where to move on after the
diagnostics update, on the next `GoTo[Prev]Diagnostic` action call.

As this change went unchanged for some time, another approach is tested
now, to be more integrated with inline diagnostics: now, the active
state is cleared

Same as before this change, another `GoTo[Prev]Diagnostic` action call
will be needed to re-expand a new diagnostics, but this change makes
this expansion to happen after the cursor — before the change, Zed would
continue from the stale diagnostics.

Release Notes:

- Fixed active diagnostics becoming stale

`auto` -> `stealth`
`eager_preview` -> `eager`

This PR fixes a bug where using the project diff editor to restore hunks
from a file that's not open in its own buffer would cause those reverts
to be lost once the project diff drops its excerpts for that file.

The fix is to save the buffers after restoring them but before the
excerpts are (potentially) dropped. This is done for the project diff
editor only. If we fail to save the affected files, we add their buffers
to the active workspace, so that the reverted contents are preserved and
the user can try again to save them.

This PR abstracts the communication layer for context servers, laying
the groundwork for supporting multiple transport mechanisms and taking
one step towards enabling remote servers.

Key changes centre around creating a new `Transport` trait with methods
for sending and receiving messages. I've implemented this trait for the
existing stdio-based communication, which is now encapsulated in a
`StdioTransport` struct. The `Client` struct has been refactored to use
this new `Transport` trait instead of directly managing stdin and
stdout.

The next steps will involve implementing an SSE + HTTP transport and
defining alternative context server settings for remote servers.
