- Subscribe to buffer LanguageChanged events so language detection that
completes later (e.g. in remote projects) triggers a kernelspec refresh
and ensures the REPL UI is populated.

Brought the Markdown output up to date with how Markdown is used in the
Agent panel. This fixed an issue with outputs that were too large for
the execution view as well as made sure that markdown would wrap.

## Motivation
This PR unifies the async execution infrastructure between GPUI and
other components that depend on the `scheduler` crate (such as our cloud
codebase). By having a scheduler that lives independently of GPUI, we
can enable deterministic testing across the entire stack - testing GPUI
applications alongside cloud services with a single, unified scheduler.
## Summary
This PR completes the integration of the `scheduler` crate into GPUI,
unifying async execution and enabling deterministic testing of GPUI
combined with other components that depend on the scheduler crate.
## Key Changes
### Scheduler Integration (Phases 1-5, previously completed)
- `TestDispatcher` now delegates to `TestScheduler` for timing, clock,
RNG, and task scheduling
- `PlatformScheduler` implements the `Scheduler` trait for production
use
- GPUI executors wrap scheduler executors, selecting `TestScheduler` or
`PlatformScheduler` based on environment
- Unified blocking logic via `Scheduler::block()`
### Dead Code Cleanup
- Deleted orphaned `crates/gpui/src/platform/platform_scheduler.rs`
(older incompatible version)
## Intentional Removals
### `spawn_labeled` and `deprioritize` removed
The `TaskLabel` system (`spawn_labeled`, `deprioritize`) was removed
during this integration. It was only used in a few places for test
ordering control.
cc @maxbrunsfeld @as-cii - The new priority-weighted scheduling in
`TestScheduler` provides similar functionality through
`Priority::High/Medium/Low`. If `deprioritize` is important for specific
test scenarios, we could add it back to the scheduler crate. Let me know
if this is blocking anything.
### `start_waiting` / `finish_waiting` debug methods removed
Replaced by `TracingWaker` in `TestScheduler` - run tests with
`PENDING_TRACES=1` to see backtraces of pending futures when parking is
forbidden.
### Realtime Priority removed
The realtime priority feature was unused in the codebase. I'd prefer to
reintroduce it when we have an actual use case, as the implementation
(bounded channel with capacity 1) could potentially block the main
thread. Having a real use case will help us validate the design.
## Testing
- All GPUI tests pass
- All scheduler tests pass
- Clippy clean

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

Release Notes:
- settings: Major internal changes to settings. The primary user-facing
effect is that some settings which did not make sense in project
settings files are no-longer read from there. (For example the inline
blame settings)

serde 1.0.221 introduced serde_core into the build graph, which should
render explicitly depending on serde_derive for faster build times an
obsolote method.
Besides, I'm not even sure if that worked for us. My hunch is that at
least one of our deps would have `serde` with derive feature enabled..
and then, most of the crates using `serde_derive` explicitly were also
depending on gpui, which depended on `serde`.. thus, we wouldn't have
gained anything from explicit dep on `serde_derive`

Closes#37829
This PR introduces and exposes `REPLSettings` to control the number of
lines and columns in the REPL. These settings are integrated into the
existing configuration system, allowing for customization and management
through the standard settings interface.
#### Changes
- Added `REPLSettings` struct with `max_number_of_lines` and
`max_number_of_columns` fields.
- Integrated `REPLSettings` with the settings system by implementing the
`Settings` trait.
- Ensured compatibility with the workspace and existing settings
infrastructure.
Release Notes:
- Add configuration "repl" to settings to configure max lines and
columns for repl.

We're seeing panics caused by a buggy implementation of AsyncWrite
that is being passed to rustls:
https://github.com/rustls/rustls/issues/2316#issuecomment-2662838186
One hypothesis was that we're using (comparatively) non-standard async
tools for connecting over websockets; so this attempts to make us be
(comparitvely) more standard.

This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.
To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.
Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)
One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.
TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL

Some VPN configurations require that websockets present a user agent.
This adds it in directly for the repl usage. I wish there was a way to
reuse the user agent from the `cx.http_client`, but I'm not seeing a
simple way to do that for the moment since it's not on the `HttpClient`
trait.
No release notes since this feature hasn't been announced/exposed.

This PR introduces a unified interface for both native and remote
kernels through the `RunningKernel` trait. When either the native kernel
or the remote kernels are started, they return a `Box<dyn
RunningKernel>` to make it easier to work with the session. As a bonus
of this refactor, I've dropped some of the mpsc channels to instead opt
for passing messages directly to `session.route(message)`. There was a
lot of simplification of `Session` by moving responsibilities to
`NativeRunningKernel`.
No release notes yet until this is finalized.
* [x] Detect remote kernelspecs from configured remote servers
* [x] Launch kernel on demand
For now, this allows you to set env vars `JUPYTER_SERVER` and
`JUPYTER_TOKEN` to access a remote server. `JUPYTER_SERVER` should be a
base path like `http://localhost:8888` or
`https://notebooks.gesis.org/binder/jupyter/user/rubydata-binder-w6igpy4l/`

## Other missing features
The following is a list of missing functionality or expectations that
are out of scope for this PR.
### Python Environments
Detecting python environments should probably be done in a separate PR
in tandem with how they're used with LSP. Users likely want to pick an
environment for their project, whether a virtualenv, conda env, pyenv,
poetry backed virtualenv, or the system. Related issues:
* https://github.com/zed-industries/zed/issues/7646
* https://github.com/zed-industries/zed/issues/7808
* https://github.com/zed-industries/zed/issues/7296
### LSP Integration
* Submit `complete_request` messages for completions to interleave
interactive variables with LSP
* LSP for IPython semantics (`%%timeit`, `!ls`, `get_ipython`, etc.)
## Future release notes
- Run code in any editor, whether it's a script or a markdown document
