This PR updates the `/file` command to emit its `SlashCommandEvent`s in
a way that can actually be streamed.

Previously it was buffering up all of the events and then returning them
all at once.

Note that we still don't yet support streaming in the context editor on
`main`, so there won't be any visible changes just yet.

Release Notes:

This changes the download logic to not fetch the latest version, but to
fetch the version matching the current version of Zed.


Release Notes:

- Changed the update logic of the SSH remote server to not fetch the
latest version for a current channel, but to fetch the version matching
the current Zed version. If Zed is updated, the server is updated too.
If the server is newer than the Zed version an error will be displayed.

This fixes a debug-only panic when processing filenames. The underflow
that happens in Preview/Stable shouldn't cause any issues (other than
maybe unmarking an entry in the project panel).

Release Notes:

- Changed the update process of the remote server binary to not attempt
an update if we can detect that the current binary is used by another
process.
- Changed the update process of the remote server binary to mark the
lock file as stale in case the SSH connection of the process that
created the lock file isn't open anymore.

This PR adds the ability for editor blocks to replace lines of text, but
does not yet use that feature anywhere. We'll update assistant patches
to use replace blocks on another branch:

This restores all the init behaviour into main again. This means we
never need to call init_ui (and so we can't call it more than once).

Release Notes:

- (Nightly only) fixes a panic when using the cli to open another file
in a running zed.

This should help a bit more the discoverability of the slash commands.

Exploring using the UI font for it, as it is more common for dropdowns
and popovers throughout the app. Feeling like it makes it lighter and
also shorter in width!

- SSH Remoting: fix a bug where inerrrupting ssh connecting could leave
your local binary cached in an invalid state

This PR fixes an issue introduced in
https://github.com/zed-industries/zed/pull/18768 where the element
backgrounds colors for `ElevationIndex::ElevatedSurface` and
`ElevationIndex::Surface` were swapped.

Release Notes:

- N/A

Use `Fs` instead of `std::fs` and do entry existence checks better:
* first, check the worktree entry existence without any FS checks
* then, only for local cases, use `Fs` to check for abs_path existence
of items, in case those came from single-filed worktrees that got closed
and removed.

Remote entries do not get file existence checks, so might try opening
previously removed buffers for now.

This PR fixes a panic that could occur when trying to complete arguments
for the `/delta` slash command.

We were using `unimplemented!()` instead of providing a default no-op
implementation like we do for other slash commands that do not support
completing arguments.

Closes https://github.com/zed-industries/zed/issues/19686.

Release Notes:

- Fixed a panic that could occur when trying to complete arguments with
the `/delta` command.

This pull request does a couple of things:

- In 29c2df73e1448bb510aebfbc954deb067fc88032, we introduced a safety
guard that prevents this crash from happening again in the future by
returning an error instead of panicking when the payload is too large.
- In 3e7a2e5c3067c53bb12cd0c76c6e7b09af7c8fcf, we introduced chunking
for updates coming from SSH servers (previously, we were sending the
whole changeset and initial set of paths in their entirety).
- In 122b5b4, we introduced a panic hook that sends panics to Axiom.

For posterity, this is how we figured out what the panic was:

```
kubectl logs current-pod-name --previous --namespace=production
```

stuff!

Release Notes:

Before this change, we would save the working directory *on the client*
of each shell that was running in a terminal.

While it's technically right, it's wrong in all of these cases where
`working_directory` was used:

- in inline assistant
- when resolving file paths in the terminal output
- when serializing the current working dir and deserializing it on
restart

Release Notes:

- Fixed terminals opened on remote hosts failing to deserialize with an
error message after restarting Zed.

Closes #19017 

Release Notes:

- Fixed project panel bug when renaming files where up/down keys could
select other files.

This snuck in when Bennet and I were debugging why our connection to the
SSH host would break. We suspected that somewhere something was logging
to STDOUT and, I guess, we changed all `println!` to `eprintln!`.

Now, two weeks later, I'm sitting here, wondering why the version check
doesn't work anymore. The server always reports a version of `""`.

Turns out we take the command's STDOUT and not STDERR, which is correct.

But it also turns out we started to print the version to STDERR, which
breaks the version check.

One-character bug & one-character fix.

This PR updates the `SlashCommand` trait to use a streaming return type.

This change is just at the trait layer. The goal here is to decouple
changing the trait's API while preserving behavior on either side.

The `SlashCommandOutput` type now has two methods for converting two and
from a stream to use in cases where we're not yet doing streaming.

On the `SlashCommand` implementer side, the implements can call
`to_event_stream` to produce a stream of events based off the
`SlashCommandOutput`.

On the slash command consumer side we use
`SlashCommandOutput::from_event_stream` to convert a stream of events
back into a `SlashCommandOutput`.

The `/file` slash command has been updated to emit `SlashCommandEvent`s
directly in order for it to work properly.

Update of the SSH remoting docs

Release Notes:

Due to leaning towards `musl` builds, unit features for `zstd` and link
it statically too for Zed.

Switches us to using `-latest` tags with Anthropic models instead of
pinning to a specific date version.
See: [Anthropic Model
Docs](https://docs.anthropic.com/en/docs/about-claude/models)

This is a no-op for:
- Claude 3 Opus (`claude-3-opus-20240229`)
- Claude 3 Sonnet (`claude-3-sonnet-20240229`)
- Claude 3 Haiku (`claude-3-haiku-20240307`)

For Claude 3.5 Sonnet this will update us from
`claude-3-5-sonnet-20240620` to `claude-3-5-sonnet-20241022`. We will
also pickup any subsequent model updates automatically when Anthropic
updates the `latest` tag.

This matches the behavior for OpenAI where use `gpt-4o` as the
model_name and not `gpt-4o-2024-08-06`.

This PR adds a new `SlashCommandResult` type alias.

We're going to be changing what slash commands can return in order to
support streaming, so having this type alias in place will make that
switch a bit more neat.

Release Notes:

- N/A

This tackles an issue with us exposing unnecessary env variables in
environment which are not actually needed for tasks themselves (and may
have little utility), yet come into the way of ssh remoting.

Just polishing the UI a bit more. One drawback of this, though, is that
if you _do_ have a big nickname or server name, with this current
solution, you won't be able to see it. Ideally, we should be able to
hover over it and see it in a tooltip, but the `div` still doesn't
support that out of the box.

Hey team!

I was investigating the new node settings added in #18172, and when
trying to set the node path I noticed that the example settings in
`default.json` use the wrong key for the `node_path` - it should be
`path` instead.

See
[here](https://github.com/zed-industries/zed/blob/19eebcd349d9ea14aa9ec6e0fe178ae26945f52a/crates/zed/src/main.rs#L488)
for where the setting is used.

Release Notes:

We have to do `workspace.with_local_workspace`, otherwise we'll try to
open the settings on the remote host.


Release Notes:

- N/A

Certain files like Rust stdlib ones can be opened by cmd-clicking on
terminal, editor contents, etc.

Those files will not belong to the current worktree, so a fake worktree,
with a single file, invisible (i.e. its dir(s) will not be shown in the
UI such as project panel), will be created on the file opening.

When the file is closed, the worktree is closed and removed along the
way, so those worktrees are considered ephemeral and their ids are not
stored in the database.
This causes issues on reopening such files when they are closed. 

The PR makes Zed to fall back to opening the file by abs path when it's
not in the project metadata, but has the abs path stored in history or
in the opened items DB data.

Release Notes:

- Handle external worktree entries [re]open better

This adds the following optional setting:

```json
{
  "remote_server": {
    "download_on_host": false
  }
}
```
Right now, it's **off by default** because I haven't tested it enough.

Release Notes:

This PR main relevant change is removing the logic we had inserted for
keyboard nav scroll as that was unreliable; we need to figure out a
better solution still. I'm also removing the visible on hover behavior
for the scrollbar as that was making us lose the click and drag feature
the component has. Lastly, I added a bit of right-margin in the delete
icon button so that's not too crammed with the scrollbar.

Release Notes:

This creates a `<binary_path>.lock` file and checks for it whenever
uploading a binary.

Parameters:
- Wait for other instance to finish: 10m
- Mark lockfile as stale and ignore it after: 10m
- When waiting on another process, check every 5seconds

We can tweak all of them.

Ideally we'd have a value in the lockfile, that lets us detect whether
the other process is still there, but I haven't found something stable
yet:

- We don't have a stable PID on the server side when we run multiple
commands
- The `ControlPath` is on the client side
