Adds support for [Goto
Declaration](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_declaration)
LSP command.

I am particularly interested in [this for Rust
projects](https://rust-analyzer.github.io/manual.html#go-to-declaration),
to be able to navigate to the place where a trait method is declared,
coming from a trait method implementation.

I noticed this was something I could do in VSCode before, but was
somehow missing is Zed. Thanks to the already existing infrastructure
for Goto Definition, I just followed and copy-paste-adapted it for Goto
Declaration.

As a bonus, I added `ctrl-F12` and `alt-ctrl-F12` as default macOS
keybindings for `GoToDeclaration` and `GoToDeclarationSplit`,
respectively. They are not keybindings from another editor, but I
figured they made sense to be grouped along with the other *F12
commands.

### Release Notes:

- Added "Go to declaration" editor action.
- vim: Breaking change to keybindings after introduction of the `Go to
declaration` editor action. The new keybindings are the following (and
can be found [here](https://zed.dev/docs/vim), alongside the other key
bindings):
  - `g d` - Go to definition
  - `g D` - Go to declaration
  - `g y` - Go to type definition
  - `g I` - Go to implementation

Hi, this pull request adds support for RBS files for the Ruby language.
[RBS](https://github.com/ruby/rbs) is a language to describe the
structure of Ruby programs.

This pull request:

- adds a new grammar to the Ruby extension for RBS
https://github.com/joker1007/tree-sitter-rbs
- configures the Ruby extension to use the added grammar.

Release Notes:

This PR adds support for additional providers to the LLM service:

- OpenAI
- Google
- Custom Zed models (through Hugging Face)

Release Notes:

- N/A

This PR introduces a separate backend service for making LLM calls.

It exposes an HTTP interface that can be called by Zed clients. To call
these endpoints, the client must provide a `Bearer` token. These tokens
are issued/refreshed by the collab service over RPC.

We're adding this in a backwards-compatible way. Right now the access
tokens can only be minted for Zed staff, and calling this separate LLM
service is behind the `llm-service` feature flag (which is not
automatically enabled for Zed staff).

This PR makes it so any Stripe events we receive that occurred over an
hour ago are marked as processed.

We don't want to process an old event long after it occurred and
potentially overwrite more recent updates.

This also makes running collab locally a bit nicer, as we won't be
getting errors for a bunch of older events that will never get processed
successfully.

The period after time after which we consider an event "stale" can be
modified, as needed.

This PR changes how we report the `geoip_country_code` in the tracing
spans.

I wasn't seeing it come through in the logs, and I think it was because
we didn't declare the field on the initial span.

This PR removes the old model selector code, as it was no longer used
after #15693.

Release Notes:

- N/A

This updates the model selector to be a combobox (filterable list)

This PR causes the following regression: There is no longer a message in
the inline assistant explaining context is included from the assistant
panel. Will follow up with some sort of solution soon.

- Shows notice if user is signed-out and (does not have provider OR
provider is zed.dev) and tells user to sign in

We no longer have to use line height calculations now that
https://github.com/zed-industries/zed/pull/15536 is in. Blocks resize
according to their content. This fixes up some of the rendering issues
on plaintext outputs as well.

Release Notes:

- Fix repl plain text output wrapping around and covering editor text

This PR changes the fallback color for the
`title_bar.inactive_background` theme property so that the title bar
doesn't just disappear when a theme doesn't have a value set.

You're welcome, @naomieow.

Release Notes:

- linux: Changed the fallback color of `title_bar.inactive_background`
to a non-transparent value.

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 removes some `unwrap`s while loading the built-in step
resolution prompt.

While these `unwrap`s are safe today, they are relying on some implicit
contracts that might change in the future. We're using this in a context
where it's easy to propagate an error upwards, so we may as well avoid
the `unwrap`s entirely and use a `Result`.

Release Notes:

- N/A

Change the terminal assistant settings icon so its consistent with the one we're using on the inline assistant.

This PR moves the `copilot_chat_config_path` out of `paths` and into

`paths`.

This commit weaves through new APIs for language::BufferChunks, multi_buffer::MultiBufferChunks and inlay_map::InlayChunks that allow seeking with an upper-bound. This allows us to omit doing syntax highligting and looking up diagnostics for folded ranges. This in turn directly improves performance of assistant panel with large contexts.

Release Notes:

- Fixed poor performance when editing in the assistant panel after
inserting large files using slash commands

This PR updates the `LanguageModel` trait with a new method for denoting
the availability of a model.

Right now we have two variants:

- `Public` for models that have no additional restrictions (other than
their respective setup/authentication requirements)
- `RequiresPlan` for models that require a specific Zed plan

This PR updates the extension API to make the `worktree` argument to
`run_slash_command` optional.

We may not always have a worktree, and not all slash commands need them,
so by making it optional we can allow individual slash commands to
decide what to do when there is no worktree.

Release Notes:

- N/A

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:

- The secrets portal is only used if the application is sandboxed
without access to the org.freedesktop.secrets on the host but as zed is
not really working correctly if sandboxed as is, it is better to
completely omit that part
- The org.freedestkop.secrets is not a portal but a spec file that is
implemented by both gnome in gnome-keyring, kde in kwallet but also by
other password managers like keepassxc and it is a requirement for a
"correctly" set up linux desktop so just remove that wrongly documented
bit
