Closes #34881

For horizontal scroll, we weren't keeping track of the `local` bool, so
whenever the agent tries to autoscroll horizontally, it would be seen as
a user scroll event resulting in unfollow.

Release Notes:

- Fixed an issue where the Follow Agent could unexpectedly stop
following during edits.

Closes #31108

The `num_tokens_from_messages` method we use from `tiktoken-rs` creates
new BPE every time that method is called. This creation of BPE is
expensive as well as has some underlying issue that keeps memory from
releasing once the method is finished, specifically noticeable on Linux.
This leads to a gradual increase in memory every time that method is
called in my case around +50MB on each call. We call this method with
debounce every time user types in Agent Panel to calculate tokens. This
can add up really fast.

This PR lands quick fix, while I/maintainers figure out underlying
issue. See upstream discussion:
https://github.com/zurawiki/tiktoken-rs/issues/39.

Here on fork https://github.com/zed-industries/tiktoken-rs/pull/1,
instead of creating BPE instances every time that method is called, we
use singleton BPE instances instead. So, whatever memory it is holding
on to, at least that is only once per model.

Release Notes:

- Fixed issue where Agent Panel would cause high memory consumption over
prolonged use.

Switch our Linux aarch_64 release builds from Linux on Graviton (32
vCPU, 64GB) to Linux running on Apple M4 Pro (8vCPU, 32GB). Builds are
faster (20mins vs 30mins) for the same cost (960 unit minutes;
~$0.96/ea).

Release Notes:

- N/A

This PR fixes an issue where Edit Predictions would not be available in
buffers that were opened when the workspace loaded.

The issue was that there was a race condition between fetching/setting
the authenticated user state and when we assigned the Edit Prediction
provider to buffers that were already opened.

We now wait for the event that we emit when we have successfully loaded
the user in order to assign the Edit Prediction provider, as we'll know
the user has been loaded into the `UserStore` by that point.

Closes https://github.com/zed-industries/zed/issues/35883

Release Notes:

- Fixed an issue where Edit Predictions were not working in buffers that
were open when the workspace initially loaded.

This PR makes it so we refresh the LLM token upon receiving a
`UserUpdated` message from Cloud over the WebSocket connection.

Release Notes:

This PR updates signed-out state of the Collab panel to show when not
connected to Collab, as opposed to just when the user is signed-out.

Release Notes:

- N/A

This PR makes it so that only Zed staff connect to Collab automatically.

Anyone else can connect to Collab manually when they want to collaborate
(but this is not required for using Zed's LLM features).

This PR adds types for the Cloud WebSocket protocol to the
`cloud_api_types` crate.

Release Notes:

- N/A

This uses the `current_user` watch in the `UserStore` instead of looping
every 100ms in order to detect if the user had signed in.

We are changing this because we noticed it was causing the deterministic
executor in tests to never detect a "parking with nothing left to run"
situation.

This seems better in production as well, especially for users who never
sign in.

In #35471, we added a new `AuthenticationError` variant to the client
enum `Status`, but the reconnection logic was ignoring it when
determining whether to reconnect.

This pull request fixes that regression and introduces test coverage for
this case.

Release Notes:

- N/A

This fixes a regression introduced in
https://github.com/zed-industries/zed/pull/35471, where we treated
stored credentials as invalid when failing to retrieve the authenticated
user for any reason. This had the side effect of triggering the auth
flow even when e.g. the client/server had temporary networking issues.

This pull request changes the logic to only trigger authentication when
getting a 401 from the server.

Release Notes:

- N/A

This pull request should be idempotent, but lays the groundwork for
avoiding to connect to collab in order to interact with AI features
provided by Zed.

This PR reworks authentication for developing Zed against a local
version of Cloud and/or Collab.

You will still connect the same way—using the `zed-local` script—but
will need to be running an instance of Cloud locally.

This PR updates the Zed Edit Prediction provider to acquire the LLM
token from Cloud instead of Collab to allow using Edit Predictions even
when disconnected from or unable to connect to the Collab server.

This PR updates the user menu in the title bar to show the plan from the
`CloudUserStore` instead of the `UserStore`.

We're still leveraging the RPC connection to listen for `UpdateUserPlan`
messages so that we can get live-updates from the server, but we are
merely using this as a signal to re-fetch the information from Cloud.

Release Notes:

- N/A

This PR adds more data to the `GetAuthenticatedUserResponse`.

We now return more information about the authenticated user, as well as
their plan information.

Release Notes:

- N/A

This PR makes it so we don't keep fetching the authenticated user once
we have them.

Release Notes:

- N/A

This PR updates the user menu in the title bar to base the "signed in"
state on the user in the `CloudUserStore` rather than the `UserStore`.

This makes it possible to be signed-in—at least, as far as the user menu
is concerned—even when disconnected from Collab.

Release Notes:

- N/A

This PR adds a new `CloudUserStore` for storing information about the
user retrieved from Cloud instead of Collab.

Release Notes:

- N/A

This PR adds two new crates for interacting with Cloud:

- `cloud_api_client` - The client that will be used to talk to Cloud.
- `cloud_api_types` - The types for the Cloud API that are shared
between Zed and Cloud.

Release Notes:

- N/A

We used to not respond at all to requests that we didn't have a handler
for, which is yuck. It may have left the language server waiting for the
response for no good reason. The other (worse) finding is that we did
not have a full definition of an Error type for LSP, which made it so
that a spec-compliant language server would fail to deserialize our
response (with an error). This then could lead to all sorts of
funkiness, including hangs and crashes on the language server's part.

In response to an ongoing BuildJet outage, consider migrating CI to
GitHub hosted runners.

Also includes revert of (causing flaky tests):
- https://github.com/zed-industries/zed/pull/35741

Downsides:
- Cost (2x)
- Force migration to Ubuntu 22.04 from 20.04 will bump our glibc minimum
from 2.31 to 2.35. Which would break RHEL 9.x (glibc 2.34), Ubuntu 20.04
(EOL) and derivatives.

Fixes a regression introduced in
https://github.com/zed-industries/zed/pull/34992

Paths are rendered first to an intermediate MSAA texture, and then
copied to the final drawable. Because paths can have transparency, it's
important that pixels are not copied repeatedly if paths have
overlapping bounding boxes. When N paths have the same draw order, we
infer that they must have disjoint bounding boxes, so that we can copy
them each individually (as opposed to copying a single rect that
contains them all). Previously, the bounding box that we were using to
copy paths was not accounting for the path's content mask (but it is
accounted for in the bounds tree that determines their draw order).

This cause bugs like this, where certain path pixels spuriously had
their opacity doubled:

https://github.com/user-attachments/assets/d792e60c-790b-49ad-b435-6695daba430f

This PR fixes that bug.

Release Notes:

- Fixed a bug where a selection's opacity was computed incorrectly when
it overlapped with another editor's selections in a certain way.

Closes #34108
Closes #33234

This PR fixes a bug where a file remained in a Created state after
accept, causing following reject actions to incorrectly delete the file
instead of reverting back to previous state. Now it changes it to
Modified state upon "Accept All" and "Accept Hunk" (when all edits are
accepted).

- [x] Tests

Release Notes:

- Fixed issue where rejecting AI edits on newly created files would
delete the file instead of reverting to previous accepted state.
