This PR makes it possible to use different LLM models in the agent
panels of two different projects, simultaneously. It also properly
restores a thread's original model when restoring it from the history,
rather than having it use the default model. As before, newly-created
threads will use the current default model.
Release Notes:
- Enabled different project windows to use different models in the agent
panel
- Enhanced the agent panel so that when revisiting old threads, their
original model will be used.

Previously, if you clicked on a user message to edit it, and then, while
the user message has the editor pending, sent a new message via the
textarea, the whole thread would be grayed out because we hadn't
dismissed the to-be-edited pending user message. That's now fixed.
Release Notes:
- agent: Fixed a bug that would make the whole thread be grayed out upon
sending a new message while a user message had a pending edit.
This moves summarization task management out of `context_store`. The
code there was draining a Vec of tasks to block on, but this is no
longer a good fit for message_editor's context loading. It needs to be
able to repeatedly await on the thread summarization tasks involved in
the context.
Discussed with Danilo, and he thinks it'd be good to remove the current
"Summarizing context" anyway since it causes layout shift. If message
send is blocked on summarizing, the pulsing context pill is sufficient
for now. This UI change made this overall change more straightforward.
Release Notes:

This change updates the system prompt to conditionally include
`grep`-related instructions based on whether the `grep` tool is enabled.
Implementation details:
1. Add a `has_tool` handlebars helper.
2. Pass the `model` to all locations where the prompt is built.
3. Use `{{#if has_tool "grep"}}` in the system prompt to gate
`grep`-specific instructions.
Testing:
- Unit tests for the `hasTool` helper.
- Unit tests to verify that `grep`-related instructions are included /
omitted from the prompt as appropriate.
- Manual agent evaluation:
- Setup: Asked the Agent "List all impls of MyTrait in the project"
using a custom "No tools" profile (all tools disabled).
- Before the change: The Agent attempted to call `grep`, encountered an
error, then realized the tool was unavailable.
- After the change: The Agent immediately asked to enable a search tool.
Note: in principle, `grep`/`read_file` tool descriptions alone might be
enough, but to confirm this we need more evaluation. If it turns out to
be true, we'll be able to remove grep-specific instructions from the
system prompt and undo this change.
Release Notes:

* Brings back hover popover of selection context.
* Adds hover popover for symbol, rules, and thread context.
* Makes context attached to messages display the names / content at
attachment time.
* Adds the file name as the displayed parent of symbol context.
* Brings back `impl Component for AddedContext`

This also fixes a little UI bug where the text thread title would push
the buttons away from the UI when there was still space.
Release Notes:
- agent: Made text thread titles editable again.

I haven't yet added a default binding for the new command. #27797 added `:ls` and
`:buffers` which in my opinion should use the global searchable version
given that that matches the vim semantics of those commands better than
just showing the tabs in the local pane.
There's also a question of what to do when you select a tab from another
pane, should the focus jump to that pane or should that tab move to the
currently focused pane? For now I've implemented the former.
Release Notes:
- Added `tab_switcher::ToggleAll` to search open tabs from all panes and focus the selected one.

When using the agent with a project shared by a collaborator, rules file

Release Notes:
- Fixed rules file loading when using the agent with a project shared by
a collaborator.
Since #28065 merged we've seen deadlocks inside iconv when opening Zed
in a repository containing many submodules. These calls to iconv happen
inside libgit2, in our implementations of the methods `head_sha`,
`merge_head_shas`, and `show` on `RealGitRepository`. This PR moves
those methods to use the git CLI instead, sidestepping the issue. For
the sake of efficiency, a new `revparse_batch` method is added that uses
`git cat-file` to resolve several ref names in one invocation. I
originally intended to make `show` operate in batch mode as well (or
instead), but I can't see a good way to do that with the git CLI; `git
show` always bails on the first ref that it can't resolve, and
`for-each-ref` doesn't support symbolic refs like `HEAD`.
Separately, I removed the calls to `show` in `MergeDetails::load`, going
back to only loading the SHAs of the various merge heads. Loading full
commit details was intended to support the inlays feature that ended up
being cut from #28065, and we can add it back in when we need it.

Previously, all MCP tools would be completed regardless if they were
disabled/enabled for the profile. This meant that the "Write" profile
was always using all MCP tools, even if you disabled them in the
settings.
Now, when `enable_all_context_servers` is set to `true`, we will enable
all tools from all MCP servers by default but disable the ones that are
explicitly disabled for the profile.
Also fixes an issue where the tools would not show up as enabled when
using `enable_all_context_servers: true`
Release Notes:
- agent: Fix an issue where MCP tools could not be enabled/disabled
This PR adds the `FeatureFlag` suffix to the feature flag types that

This PR removes two fields from JSON schemas (`$schema` and `title`),
which are not expected by any model provider, but were spuriously
included by our JSON schema library, `schemars`.
These added noise to requests and cost wasted input tokens.
### Old
```json
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "FetchToolInput",
"type": "object",
"required": [
"url"
],
"properties": {
"url": {
"description": "The URL to fetch.",
"type": "string"
}
}
}
```
### New:
```json
{
"properties": {

Simplifies the data structures involved in agent context by removing
caching and limiting the use of ContextId:
* `AssistantContext` enum is now like an ID / handle to context that
does not need to be updated. `ContextId` still exists but is only used
for generating unique `ElementId`.
* `ContextStore` has a `IndexMap<ContextSetEntry>`. Only need to keep a
`HashSet<ThreadId>` consistent with it. `ContextSetEntry` is a newtype
wrapper around `AssistantContext` which implements eq / hash on a subset
of fields.
* Thread `Message` directly stores its context.
Fixes the following bugs:
* If a context entry is removed from the strip and added again, it was
reincluded in the next message.
* Clicking file context in the thread that has been removed from the
context strip didn't jump to the file.
* Refresh of directory context didn't reflect added / removed files.
* Deleted directories would remain in the message editor context strip.
* Token counting requests didn't include image context.
* File, directory, and symbol context deduplication relied on
`ProjectPath` for identity, and so didn't handle renames.
* Symbol context line numbers didn't update when shifted
Known bugs (not fixed):
* Deleting a directory causes it to disappear from messages in threads.
Fixing this in a nice way is tricky. One easy fix is to store the
original path and show that on deletion. It's weird that deletion would
cause the name to "revert", though. Another possibility would be to
snapshot context metadata on add (ala `AddedContext`), and keep that
around despite deletion.

We used to insert empty user messages into the `Thread::messages` `Vec`
when tools finished running and then we would attach the results when
creating the request. This approach was very easy to mess up during
state handling, leading to empty user messages displayed in the
conversation and API failures.
Instead, we will no longer insert actual user messages for tool results
to the `Thread`, and will only do this on the fly when creating the
model request. This simplifies a lot of code and show fix the mentioned
errors.
Release Notes:
- agent: Improve reliability of LLM requests when including tool results

This is to enable alternative streaming solutions at the application
layer. I'm not sure we really should have performed parsing of the input
at this layer. Either way I want to experiment with streaming approaches
in a separate crate on a branch, and this will help.

Things this doesn't currently handle:
- [x] ~testing~
- ~we really need an snapshot test that takes a vscode settings file
with all options that we support, and verifies the zed settings file you
get from importing it, both from an empty starting file or one with lots
of conflicts. that way we can open said vscode settings file in vscode
to ensure that those options all still exist in the future.~
- Discussed this, we don't think this will meaningfully protect us from
future failures, and we will just do this as a manual validation step
before merging this PR. Any imports that have meaningfully complex
translation steps should still be tested.
- [x] confirmation (right now it just clobbers your settings file
silently)
- it'd be really cool if we could show a diff multibuffer of your
current settings with the result of the vscode import and let you pick
"hunks" to keep, but that's probably too much effort for this feature,
especially given that we expect most of the people using it to have an
empty/barebones zed config when they run the import.
- [x] ~UI in the "welcome" page~
- we're planning on redoing our welcome/walkthrough experience anyways,
but in the meantime it'd be nice to conditionally show a button there if
we see a user level vscode config
- we'll add it to the UI when we land the new walkthrough experience,
for now it'll be accessible through the action
- [ ] project-specific settings
- handling translation of `.vscode/settings.json` or `.code-workspace`
settings to `.zed/settings.json` will come in a future PR, along with UI
to prompt the user for those actions when opening a project with local
vscode settings for the first time
- [ ] extension settings
- we probably want to do a best-effort pass of popular extensions like
vim and git lens
- it's also possible to look for installed/enabled extensions with `code
--list-extensions`, but we'd have to maintain some sort of mapping of
those to our settings and/or extensions
- [ ] LSP settings
- these are tricky without access to the json schemas for various
language server extensions. we could probably manage to do translations
for a couple popular languages and avoid solving it in the general case.
- [ ] platform specific settings (`[macos].blah`)
- this is blocked on #16392 which I'm hoping to address soon
- [ ] language specific settings (`[rust].foo`)
- totally doable, just haven't gotten to it yet
~We may want to put this behind some kind of flag and/or not land it
until some of the above issues are addressed, given that we expect
people to only run this importer once there's an incentive to get it
right the first time. Maybe we land it alongside a keymap importer so
you don't have to go through separate imports for those?~
We are gonna land this as-is, all these unchecked items at the bottom
will be addressed in followup PRs, so maybe don't run the importer for
now if you have a large and complex VsCode settings file you'd like to
import.
Release Notes:
- Added a VSCode settings importer, available via a
`zed::ImportVsCodeSettings` action

Our provider code in `language_models` filters out messages for which
`LanguageModelRequestMessage::contents_empty` returns `false`. This
doesn't seem wrong by itself, but `contents_empty` was returning `false`
for messages whose first segment didn't contain non-whitespace text even
if they contained other non-empty segments. This caused requests to fail
when a message with a tool call didn't contain any preceding text.
