String panics are a non-trivial percentage of the crashes we see at Zed,
and
doubly unfortunately they may incidentally include the contents of a
user's
buffer.
Although this hasn't happened yet (to my knowledge), I don't want to be
in the position of having received sensitive information this way.

Remove the separate `AgentGitWorktreesFeatureFlag` and replace all its
checks with the existing `AgentV2FeatureFlag`. The git worktree
functionality is now gated behind the same flag as agent v2.
Changes:
- Removed `AgentGitWorktreesFeatureFlag` from `feature_flags`
- Replaced all `has_flag::<AgentGitWorktreesFeatureFlag>()` checks with
`has_flag::<AgentV2FeatureFlag>()`
- Simplified toolbar condition that was redundantly checking both flags
- Updated tests accordingly
Closes AI-73

This PR removes the `cloud-thinking-effort` feature flag to ship the
thinking effort UI for the Zed provider.
Release Notes:
- Added support for controlling thinking effort levels with supported
models using the Zed provider.
Accidentally committed the feature flag change in
https://github.com/zed-industries/zed/pull/49100 as I had it turned to
true for local testing. This PR makes it turned off to staff again,
sorry!

This PR renames the `cloud-thinking-toggle` feature flag to
`cloud-thinking-effort`.
This feature flag has expanded slightly in scope, so we want the name to
be more representative of what it gates.

This PR adds a thinking toggle for controlling whether to use thinking
for a model in the Zed provider:

src="https://github.com/user-attachments/assets/9aa543fe-e708-4840-8b38-1a6fbcb78388"
/>
Previously we would create separate "Thinking" variants of the models
that supported thinking in the model selector.
This only applies to Anthropic models in the Zed provider, currently.
This is gated behind the `cloud-thinking-toggle` feature flag.

## Summary
Implements user-defined slash commands for the agent panel. Users can
create markdown files in `~/.config/zed/commands/` (user-wide) or
`.zed/commands/` (project-specific) that expand into templated text when
invoked via `/command_name` in the chat interface.
## Features
- **File-based commands**: Create `.md` files that become slash commands
- **Template expansion**: Use `$1`, `$2`, etc. for positional arguments,
or `$ARGUMENTS` for all args
- **Namespacing**: Subdirectories create namespaced commands (e.g.,
`frontend/component.md` → `/frontend:component`)
- **Project & user scopes**: Project commands in `.zed/commands/`, user
commands in config dir
- **Claude compatibility**: Can symlink `~/.claude/commands/` for
compatibility
- **Caching**: Commands are cached and watched for file changes
- **Error handling**: Graceful degradation with error display in UI
## Feature Flag
Behind `user-slash-commands` feature flag.
## Testing
52 unit/integration tests covering parsing, validation, expansion, file
loading, symlinks, and error handling.

Adds a very simple diff review button behind a feature flag, which
appears in the gutter of people who have the flag (currently just me;
it's not even enabled for staff, since it doesn't do anything yet).
Mostly this PR just adds the feature flag, the button, and tests.

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.

This PR removes the experimental jj bookmark picker that was added in
#30883.
This was just an exploratory prototype and while I would like to have
native jj UI at some point, I don't know when we'll get back to it.
Release Notes:

This removes the `gemini-and-native` and `claude-code` feature flags.
Also, I removed a bunch of unused agent1 code that we do not need
anymore.
Initially I wanted to remove much more of the `agent` code, but noticed
some things that we need to figure out first:
- The inline assistant + context strip use `Thread`/`ContextStore`
directly
- We need some replacement for `ToolWorkingSet`, so we can access
available tools (as well as context server tools) in other places, e.g.
the agent configuration and the configure profile modal
Release Notes:
- N/A
This PR moves the feature flag definitions to their own module so that
they aren't intermingled with the feature flag infrastructure itself.
