This PR overhauls extension registration in order to make it more
modular.
The `extension` crate now contains an `ExtensionHostProxy` that can be
used to register various proxies that the extension host can use to
interact with the rest of the system.
There are now a number of different proxy traits representing the
various pieces of functionality that can be provided by an extension.
The respective crates that provide this functionality can implement
their corresponding proxy trait in order to register a proxy that the
extension host will use to register the bits of functionality provided
by the extension.

This PR extracts the `ExtensionSlashCommand` implementation to the
`assistant_slash_command` crate.
The slash command related methods have been added to the `Extension`
trait. We also create separate data types for the slash command data
within the `extension` crate so that we can talk about them without
depending on the `extension_host` or `assistant_slash_command`.

This PR adds support for streaming output from slash commands
In this PR we are focused primarily on the interface of the
`SlashCommand` trait to support streaming the output. We will follow up
later with support for extensions and context servers to take advantage
of the streaming nature.

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.

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.

Fixes:
- [x] an issue where directories would only match by prefix, causing
both a directory and a file to be matched if in the same directory
- [x] An issue where you could not continue a file completion when
selecting a directory, as `tab` on a file would always run the command.
This effectively disabled directory sub queries.
- [x] Inconsistent rendering of files and directories in the slash
command

This commit proposes the addition of "context serveres" and the
underlying protocol (model context protocol). Context servers allow
simple definition of slash commands in another language and running
local on the user machines. This aims to quickly prototype new commands,
and provide a way to add personal (or company wide) customizations to
the assistant panel, without having to maintain an extension. We can
use this to reuse our existing codebase, with authenticators, etc and
easily have it provide context into the assistant panel.
As such it occupies a different design space as extensions, which I
think are
more aimed towards long-term, well maintained pieces of code that can be
easily distributed.
It's implemented as a central crate for easy reusability across the
codebase
and to easily hook into the assistant panel at all points.
Design wise there are a few pieces:
1. client.rs: A simple JSON-RPC client talking over stdio to a spawned
server. This is
very close to how LSP work and likely there could be a combined client
down the line.
2. types.rs: Serialization and deserialization client for the underlying
model context protocol.
3. protocol.rs: Handling the session between client and server.
4. manager.rs: Manages settings and adding and deleting servers from a
central pool.
A server can be defined in the settings.json as:
```
"context_servers": [
{"id": "test", "executable": "python", "args": ["-m", "context_server"]
]
```
## Quick Example
A quick example of how a theoretical backend site can look like. With
roughly 100 lines
of code (nicely generated by Claude) and a bit of decorator magic (200
lines in total), one
can come up with a framework that makes it as easy as:
```python
@context_server.slash_command(name="rot13", description="Perform a rot13 transformation")
@context_server.argument(name="input", type=str, help="String to rot13")
async def rot13(input: str) -> str:
return ''.join(chr((ord(c) - 97 + 13) % 26 + 97) if c.isalpha() else c for c in echo.lower())
```
to define a new slash_command.
## Todo:
- Allow context servers to be defined in workspace settings.
- Allow passing env variables to context_servers

This PR:
- Makes slash commands easier to compose by adding a concept,
`CompletionIntent`. When using `tab` on a completion in the assistant
panel, that completion item will be expanded but the associated command
will not be run. Using `enter` will still either run the completion item
or continue command composition as before.
- Fixes a bug where running `/diagnostics` on a project with no
diagnostics will delete the entire command, rather than rendering an
empty header.
- Improves the autocomplete rendering for files, showing when
directories are selected and re-arranging the results to have the file
name or trailing directory show first.

This PR makes it so we normalize the line endings for prompts to LFs
(`\n`) when we load a prompt from the library.
In some cases, prompts could end up with CRLF (`\r\n`) line endings.
When these prompts were used with the `/prompt` slash command and
summarily run, the prompt text would be converted into a rope, causing
the line endings to be normalized to LFs.
However, this would happen _after_ the ranges for the
`SlashCommandOutputSection`s were computed based on the text that still
contained the CRLFs. This would then cause these ranges to be invalid
for the text with the normalized endings, resulting in a panic when
converting them to anchors.
Fixes https://github.com/zed-industries/zed/issues/15652.

This PR fixes an issue where slash commands were not able to run when
Zed did not have any worktrees opened.
This requirement was only necessary for slash commands originating from
extensions, and we can enforce the presence of a worktree just for
those:

This pull request introduces collaboration for the assistant panel by
turning `Context` into a CRDT. `ContextStore` is responsible for sending
and applying operations, as well as synchronizing missed changes while
the connection was lost.
Contexts are shared on a per-project basis, and only the host can share
them for now. Shared contexts can be accessed via the `History` tab in
the assistant panel.

This PR improves the completions for arguments in the `/docs` slash
command.
We achieved this by extending the `complete_argument` method on the
`SlashCommand` trait to return a `Vec<ArgumentCompletion>` instead of a
`Vec<String>`.
In addition to the completion `label`, `ArgumentCompletion` has two new
fields that are can be used to customize the completion behavior:
- `new_text`: The actual text that will be inserted when the completion
is accepted, which may be different from what is shown by the completion
label.
- `run_command`: Whether the command is run when the completion is
accepted. This can be set to `false` to allow accepting a completion
without running the command.

Files included with the diagnostics command now include the worktree
name, making it more consistent with the way other commands work

This could still use some improvement UI-wise but the user experience
should be a lot better.
- [x] Show in "Window" application menu
- [x] Load prompt as it's selected in the picker
- [x] Refocus picker on `esc`
- [x] When creating a new prompt, if a new prompt already exists and is
unedited, activate it instead
- [x] Add `/default` command
- [x] Evaluate /commands on prompt insertion
- [x] Autocomplete /commands (but don't evaluate) during prompt editing
- [x] Show token count using the settings model, right-aligned in the
editor
- [x] Picker
- [x] Sorted alpha
- [x] 2 sublists
- Default
- Empty state: Star a prompt to add it to your default prompt
- Otherwise show prompts with star on hover
- All
- Move prompts with star on hover
Release Notes:
- N/A
- Confirming a completion now runs the command immediately
- Hitting `enter` on a line with a command now runs it
- The output of commands gets folded away and replaced with a custom
placeholder
- Eliminated ambient context

This PR adds initial support for defining slash commands for the
Assistant from extensions.
Slash commands are defined in an extension's `extension.toml`:
```toml
[slash_commands.gleam-project]
description = "Returns information about the current Gleam project."
requires_argument = false
```
and then executed via the `run_slash_command` method on the `Extension`
trait:
```rs
impl Extension for GleamExtension {
// ...
fn run_slash_command(
&self,
command: SlashCommand,
_argument: Option<String>,
worktree: &zed::Worktree,
) -> Result<Option<String>, String> {
match command.name.as_str() {
"gleam-project" => Ok(Some("Yayyy".to_string())),
command => Err(format!("unknown slash command: \"{command}\"")),
}
}
}
```
