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.

There's probably more to do to fully make the transition, and we'll
still debate a bit internally whether this is the name, but just opening
this PR up now for visibility.

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

Follow-up to https://github.com/zed-industries/zed/pull/29165 where the
user message design is simplified even more. The edit button is not
visible anymore, and you can click on the whole message block to edit a
message.

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

Release Notes:
- Improved performance of agent checkpoint creation.
- Fixed a bug that sometimes caused accidental deletions when restoring
to a previous agent checkpoint.
- Fixed a bug that caused checkpoints to be visible in the Git history.

returned from the API instead of basing it off the plan.
This will allow limits to be updated from the server rather than being
embedded in the client.

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.
Release Notes:
- N/A
* Adds a fast / cheaper model to providers and defaults thread
summarization to this model. Initial motivation for this was that
https://github.com/zed-industries/zed/pull/29099 would cause these
requests to fail when used with a thinking model. It doesn't seem
correct to use a thinking model for summarization.
* Skips system prompt, context, and thinking segments.
* If tool use is happening, allows 2 tool uses + one more agent response
before summarizing.
Downside of this is that there was potential for some prefix cache reuse
before, especially for title summarization (thread summarization omitted
tool results and so would not share a prefix for those). This seems fine
as these requests should typically be fairly small. Even for full thread
summarization, skipping all tool use / context should greatly reduce the
token use.
Release Notes:
- N/A
Previously, we were including the dummy text "Here are the tool
results." whenever reporting tool call results. I'm worried this is
adding noise and confusing the model, because the user didn't actually
say anything. This inserts an empty message to be populated later. My
preference would be something less stateful, where tool results (or
batches of them requested simultaneously) would be sent to the model as
soon as they were ready, without bothering to do this message
association dance. But for now, this seems to work.
Release Notes:
- N/A
Looks like the required backend component of this was deployed.

This is based on user feedback that the Agent Panel menu was only
linking to extensions as a way to add MCP servers while we also support
adding "custom" servers, too, which don't go through the extensions
flow.
Release Notes:
- N/A
Now that we've established a proper eval in tree, this PR is reboots of
our agent loop back to a set of minimal tools and simpler prompts. We
should aim to get this branch feeling subjectively competitive with
what's on main and then merge it, and build from there.
Let's invest in our eval and use it to drive better performance of the
agent loop. How you can help: Pick an example, and then make the outcome
faster or better. It's fine to even use your own subjective judgment, as
our evaluation criteria likely need tuning as well at this point. Focus
on making the agent work better in your own subjective experience first.
Let's focus on simple/practical improvements to make this thing work
better, then determine how we can craft our judgment criteria to lock
those improvements in.

Related to #28490.
- Default prompts from the prompt library are now included as "user
rules" in the system prompt.
- Presence of these user rules is shown at the beginning of the thread
in the UI.
_ Now uses an `Entity<PromptStore>` instead of an `Arc<PromptStore>`.
Motivation for this is emitting a `PromptsUpdatedEvent`.
- Now disallows concurrent reloading of the system prompt. Before this
change it was possible for reloads to race.
Release Notes:
- agent: Added support for including default prompts from the Prompt
Library as "user rules" in the system prompt.

This PR makes it so the thread summarization also reports the model
request usage, to prevent the case where the count would appear to jump
