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.

Another tiny PR for the sake of consistency :)

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.

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.

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 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
```

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.

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

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.

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.

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

Hello, this PR adds a new view to the LSP servers menu for
displaying an LSP server capabilities.

When I work on LSP stuff, quite often I need to check what capabilities
an LSP server has. Currently there is no built-in way for checking that
in Zed, and I have to use [`LSP
DevTools`](https://lsp-devtools.readthedocs.io) project. LSP DevTools
works OK but it works as a proxy between the client and the server, so
setting it up is not that easy in Zed. Zed already has many goodies for
LSP like tracing and RPC messages, so I thought that a simple view with
server capabilities could be useful too. Thanks!

Release Notes:

- Fixed directory name comparison on Linux not considering the case
([#18851](https://github.com/zed-industries/zed/issues/18851))

Caps the size of the Supermaven states buffer to 1000 elements.
Previously, the buffer would grow unbounded so for long sessions the
number of states that the Supermaven autocomplete provider maintains can
be quite large. In practice, states that are sufficiently old are so
unlikely to be visited again that we can regenerate the completion.
Thus, we can cap the buffer to 1000 elements.

multiple active billing subscriptions.

2. When creating subscriptions in response to Stripe events, we ensure
that we don't already have an active subscription.

This contains a bunch of smallish but nasty fixes:

- Heartbeat timer was never reset after first heartbeat
- Use same return value when stderr is closed as when stdout is closed
- Always check proxy process status since it should also be done when we
get to this point (either it died and our task stopped, or our task
stopped and we dropped the process handle and it was killed on drop)
- make error messages less wrongly-specific
