Introducing the Active File Context portion of #9705. When someone is in
the assistant panel it now includes the active file as a system message
on send while showing them a nice little display in the lower right:

For this iteration, I'd love to see the following before we land this:
* [x] Toggle-able context - user should be able to disable sending this
context
* [x] Show nothing if there is no context coming in
* [x] Update token count as we change items
* [x] Listen for a more finely scoped event for when the active item
changes
* [x] Create a global for pulling a file icon based on a path. Zed's
main way to do this is nested within project panel's `FileAssociation`s.
* [x] Get the code fence name for a Language for the system prompt
* [x] Update the token count when the buffer content changes
I'm seeing this PR as the foundation for providing other kinds of
context -- diagnostic summaries, failing tests, additional files, etc.
Release Notes:
- Added file context to assistant chat panel
([#9705](https://github.com/zed-industries/zed/issues/9705)).

We're doing it. Svelte support is moving into an extension. This PR
fixes some issues that came up along the way.
Notes
* extensions need to be able to retrieve the path the `node` binary
installed by Zed
* previously we were silently swallowing any errors that occurred while
loading a grammar
* npm commands ran by extensions weren't run in the right directory
* Tree-sitter's WASM stdlib didn't support a C function (`strncmp`)
needed by the Svelte parser's external scanner
* the way that LSP installation status was reported was unnecessarily
complex
Release Notes:
- Removed built-in support for the Svelte and Gleam languages, because
full support for those languages is now available via extensions. These
extensions will be suggested for download when you open a `.svelte` or
`.gleam` file.

This PR also introduces built-in tasks for Rust and Elixir. Note that
this is not a precedent for future PRs to include tasks for more
languages; we simply want to find the rough edges with tasks & language
integrations before proceeding to task contexts provided by extensions.
As is, we'll load tasks for all loaded languages, so in order to get
Elixir tasks, you have to open an Elixir buffer first. I think it sort
of makes sense (though it's not ideal), as in the future where
extensions do provide their own tasks.json, we'd like to limit the # of
tasks surfaced to the user to make them as relevant to the project at
hand as possible.
Release Notes:
- Added built-in tasks for Rust and Elixir files.
Our goal is to extract Svelte support into an extension, since we've
seen problems with the Tree-sitter Svelte parser crashing due to bugs in
the external scanner. In order to do this, we need a couple more
capabilities in LSP extensions:
* [x] `initialization_options` - programmatically controlling the JSON
initialization params sent to the language server
* [x] `prettier_plugins` - statically specifying a list of prettier
plugins that apply for a given language.
* [x] `npm_install_package`
Release Notes:
- N/A

Closes https://github.com/zed-industries/zed/issues/9458
When flying in a plane being totally offline, I've discovered that my
Rust projects do not have any LSP support and rust-analyzer disappeared
out of `~/Library/Application Support/Zed/languages/rust-analyzer/`
directory.
Looking at the
[bad.log](https://github.com/zed-industries/zed/files/14627508/bad.log),
it appears that `get_language_server_command` tries to find a newer LSP
server version and fails on
80bc6c8cc8/crates/language/src/language.rs (L339)
bailing out of all installation related-methods up to here:
80bc6c8cc8/crates/project/src/project.rs (L2916)
where the code thinks that the binary installation process had failed,
cleans the existing directory and tries to install the language server
again:

```
The PR extracts away all binary fetching-related code into a single
method that does not fail the entire `get_language_server_command` and
allows it to recover and reuse the existing binary:

Release Notes:
- Fixed language servers erased from the disk when project is opened
offline
Fixes: https://github.com/zed-industries/zed/issues/9234
This doesn't address `vue` as it has a slightly different install code,
but it should be fairly simple to add - I'll add it in in a follow-up.
This PR will allow all (except `vue`) node-based language servers to
update. It is mostly just throwing in a method into the `NodeRuntime`
trait that is used for checking if a package doesn't exist locally, or
is out of date, by checking the version against what's newest, and
installing. If any parsing of the `package.json` data fails along the
way, it assumes something has gone awry on the users system, logs the
error, and then proceeds with trying to install the package, so that
users don't get stuck on version if their package has some bad data.
Outside of adding this method, it just adds that check in all of the
language server's individual `fetch_server_binary` methods.
Release Notes:
- Added updating for node-based language servers
([#9234](https://github.com/zed-industries/zed/issues/9234)).
This fixes#9292 by adding a section to the language server settings
that allows users to specify the binary path and arguments with which to
start up a language server.
Example user settings for `rust-analyzer`:
```json
{
"lsp": {
"rust-analyzer": {
"binary": {
"path": "/Users/thorstenball/tmp/rust-analyzer-aarch64-apple-darwin",
"arguments": ["--no-log-buffering"]
}
}
}
}
```
Constraints:
* Right now this only allows ABSOLUTE paths.
* This is only used by `rust-analyzer` integration right now, but the
setting can be used for other language servers. We just need to update
the adapters to also respect that setting.
Release Notes:
- Added ability to specify `rust-analyzer` binary `path` (must be
absolute) and `arguments` in user settings. Example: `{"lsp":
{"rust-analyzer": {"binary": {"path": "/my/abs/path/rust-analyzer",
"arguments": ["--no-log-buffering"] }}}}`
([#9292](https://github.com/zed-industries/zed/issues/9292)).

Closes#5178
Release Notes:
- Added a `file_types` setting that can be used to associate languages
with file names and file extensions. For example, to interpret all `.c`
files as C++, and files called `MyLockFile` as TOML, add the following
to `settings.json`:
```json
{
"file_types": {
"C++": ["c"],
"TOML": ["MyLockFile"]
}
}
```
As with most zed settings, this can be configured on a per-directory
basis by including a local `.zed/settings.json` file in that directory.

In this PR, we've added two new methods that LSP extensions can call:
* `shell_env()`, for retrieving the environment variables set in the
user's default shell in the worktree
* `which(command)`, for looking up paths to an executable (accounting
for the user's shell env in the worktree)
To test this out, we moved the `uiua` language support into an
extension. We went ahead and removed the built-in support, since this
language is extremely obscure. Sorry @mikayla-maki. To continue coding
in Uiua in Zed, for now you can `Add Dev Extension` from the extensions
pane, and select the `extensions/uiua` directory in the Zed repo. Very
soon, we'll support publishing these extensions so that you'll be able
to just install it normally.

This PR supplements tasks with additional environment variables; ideally
we'll be able to write a task like:
`cargo test -p $ZED_CURRENT_PACKAGE -- $ZED_CURRENT_FUNCTION`
- [x] Flesh out multibuffer interactions
- [x] Add ZED_SYMBOL detection based on tree-sitter queries
- [ ] Add release note and demo
- [x] Figure out a solution for rerun dilemma - should `task: rerun`
reevaluate contexts for tasks?
This PR introduced the following variables:
- ZED_COLUMN - current line column
- ZED_ROW - current line row
and the following, which are available for buffers with associated
files:
- ZED_WORKTREE_ROOT - absolute path to the root of the current worktree.
- ZED_FILE - absolute path to the file
- ZED_SYMBOL - currently selected symbol; should match the last symbol
shown in a symbol breadcrumb (e.g. `mod tests > fn test_task_contexts`
should be equal to ZED_SYMBOL of `test_task_contexts`). Note that this
isn't necessarily a test function or a function at all.
Also, you can use them in `cwd` field of definitions (note though that
we're using https://docs.rs/subst/latest/subst/#features for that, so
don't expect a full shell functionality to work); the syntax should
match up with your typical Unix shell.
Release Notes:
- Added task contexts, which are additional environment variables set by
Zed for task execution; task content is dependent on the state of the
editor at the time the task is spawned.

This PR adds **internal** ability to run arbitrary language servers via
WebAssembly extensions. The functionality isn't exposed yet - we're just
landing this in this early state because there have been a lot of
changes to the `LspAdapter` trait, and other language server logic.
## Next steps
* Currently, wasm extensions can only define how to *install* and run a
language server, they can't yet implement the other LSP adapter methods,
such as formatting completion labels and workspace symbols.
* We don't have an automatic way to install or develop these types of
extensions
* We don't have a way to package these types of extensions in our
extensions repo, to make them available via our extensions API.
* The Rust extension API crate, `zed-extension-api` has not yet been
published to crates.io, because we still consider the API a work in
progress.

We couldn't reproduce the panic, but I believe it was possible when

After a lot of back-and-forth, this is a small attempt to implement
solutions (1) and (3) in
https://github.com/zed-industries/zed/issues/7902. The goal is to have a
minimal change that helps users get started with Zed, until we have
extensions ready.
Release Notes:
- Added detection of user-installed `gopls` to Go language server
adapter. If a user has `gopls` in `$PATH` when opening a worktree, it
will be used.
- Added detection of user-installed `zls` to Zig language server
adapter. If a user has `zls` in `$PATH` when opening a worktree, it will
be used.
Example:
I don't have `go` installed globally, but I do have `gopls`:
```
~ $ which go
go not found
~ $ which gopls
/Users/thorstenball/code/go/bin/gopls
```
But I do have `go` in a project's directory:
```
~/tmp/go-testing φ which go
/Users/thorstenball/.local/share/mise/installs/go/1.21.5/go/bin/go
~/tmp/go-testing φ which gopls
/Users/thorstenball/code/go/bin/gopls
```
With current Zed when I run `zed ~/tmp/go-testing`, I'd get the dreaded
error:

But with the changes in this PR, it works:
```

This PR adds the initial support for loading extensions in Zed.
### Extensions Directory
Extensions are loaded from the extensions directory.
The extensions directory has the following structure:
```
extensions/
installed/
extension-a/
grammars/
languages/
extension-b/
themes/
manifest.json
```
The `manifest.json` file is used internally by Zed to keep track of
which extensions are installed. This file should be maintained
automatically, and shouldn't require any direct interaction with it.
Extensions can provide Tree-sitter grammars, languages, and themes.

Release Notes:
- Added bash syntax highlighting to `.env` files.
- Added a `private_files` setting for configuring which files should be
considered to contain environment variables or other sensitive
information.
- Added a `redact_private_values` setting to add or remove censor bars
over variable values in files matching the `private_files` patterns.
-(internal) added a new `redactions.scm` query to our language support,
allowing different config file formats to indicate where environment
variable values can be identified in the syntax tree, added this query
to `bash`, `json`, `toml`, and `yaml` files.
