User-visible improvements:
- Native Agent now shows AI responses in the chat interface
- Uses configured default model from settings instead of random selection
- Streams responses in real-time as the model generates them

Technical changes:
- Implemented response stream forwarding from Thread to AcpThread
- Created Session struct to manage Thread and AcpThread together
- Added proper SessionUpdate handling for text chunks and tool calls
- Fixed model selection to use LanguageModelRegistry's default
- Added comprehensive logging for debugging model interactions
- Removed unused cwd parameter - native agent captures context differently than external agents

- Created NativeAgentServer that implements AgentServer trait
- Added NativeAgent to ExternalAgent enum
- Added Native Agent option to both the + menu and empty state view
- Added necessary dependencies (agent_servers, ui) to agent2 crate
- Added agent2 dependency to agent_ui crate
- Temporarily removed feature flag check for testing

- Renamed Agent struct to NativeAgent to better reflect its native implementation
- Renamed AgentConnection to NativeAgentConnection for consistency
- Updated all references and implementations
- Bumped agent-client-protocol version to 0.0.14

- Add public session_id() method to AcpThread to enable testing
- Fix ModelSelector methods to use async move closures properly to avoid borrow conflicts
- Add test_agent_connection that verifies:
  - Model selector is available for agent2
  - Can list available models
  - Can create threads with default model
  - Can query selected model for a session
  - Can send prompts using the selected model
  - Can cancel sessions
  - Handles errors for invalid sessions
- Remove unnecessary mut keywords from async closures

- Add ModelSelector trait to acp_thread crate with list_models, select_model, and selected_model methods
- Extend AgentConnection trait with optional model_selector() method returning Option<Rc<dyn ModelSelector>>
- Implement ModelSelector for agent2's AgentConnection using LanguageModelRegistry
- Make selected_model field mandatory on Thread struct
- Update Thread::new to require a default_model parameter
- Update agent2 to fetch default model from registry when creating threads
- Fix prompt method to use the thread's selected model directly
- All methods use &mut AsyncApp for async-friendly operations

Added Agent struct that implements the acp::Agent trait with:
- Complete: initialize (protocol handshake) and authenticate (stub auth)
- Partial: new_session (creates ID but needs GPUI context for Thread)
- Partial: cancelled (removes session but needs GPUI cleanup)
- Stub: load_session and prompt (need GPUI context integration)

The implementation uses RefCell for session management since trait methods
take &self, and Cell for simple authentication state. Templates are Arc'd
for potential Send requirements.

Next steps:
- Integrate GPUI context for Thread creation/management
- Implement content type conversions between acp and agent2
- Add proper session persistence for load_session
- Stream responses back through the protocol

Preparing for the introduction of a new Agent type that will implement
the agent-client-protocol Agent trait. The existing Thread type represents
individual conversation sessions, while Agent will manage multiple sessions.

- Remove underscore prefix from BasePrompt struct name
- Remove unused imports and variables in tests
- Fix unused parameter warning in async closure
- Rename AgentToolErased to AnyAgentTool for clarity

- Move tests from thread/tests.rs to tests/mod.rs
- Move test_tools from thread/tests/test_tools.rs to tests/test_tools.rs
- Update imports and fix compilation errors in tests
- Fix private field access by using public messages() method
- Add necessary imports for test modules

- Add cloud_llm_client dependency for CompletionIntent and CompletionMode
- Fix LanguageModelRequest initialization with missing thinking_allowed field
- Update StartMessage handling to use Assistant role
- Fix MessageContent conversions to use enum variants directly
- Fix input_schema implementation to use schemars directly
- Suppress unused variable and dead code warnings

Closes #ISSUE

Serializes the onboarding page to the database to ensure that if Zed is
closed during onboarding, re-opening Zed restores the onboarding state
and the most recently active page (Basics, Editing, etc) restored. Also
has the nice side effect of making dev a bit nicer as it removes the
need to re-open onboarding and navigate to the correct page on each
build.

The spec says:

> :arrow_left: Initialized Event
> This event indicates that the debug adapter is ready to accept
configuration requests (e.g. setBreakpoints, setExceptionBreakpoints).
>
> A debug adapter is expected to send this event when it is ready to
accept configuration requests (but not before the initialize request has
finished).

Previously in tests, `intercept_debug_sessions` was just spawning off a
background task to send the event after setting up the client, so the
event wasn't actually synchronized with the flow of messages in the way
the spec says it should be. This PR makes it so that the `FakeTransport`
injects the event right after a successful response to the initialize
request, and doesn't send it otherwise.

Closes #ISSUE

The behavior of the theme selector is documented above the function,
copied here for reference:
```rust
/// separates theme "mode" ("dark" | "light" | "system") into two separate states
/// - appearance = "dark" | "light"
/// - "system" true/false
/// when system selected:
///  - toggling between light and dark does not change theme.mode, just which variant will be changed
/// when system not selected:
///  - toggling between light and dark does change theme.mode
/// selecting a theme preview will always change theme.["light" | "dark"] to the selected theme,
///
/// this allows for selecting a dark and light theme option regardless of whether the mode is set to system or not
/// it does not support setting theme to a static value
```

This PR polishes and adds functionality to the onboarding UI with a
focus on the basic page. It added theme preview tiles, got the Vim,
telemetry, crash reporting, and sign-in button working.

The theme preview component was moved to the UI crate and it now can
have a click handler on it.

Finally, this commit also changed `client::User.github_login` and
`client::UserStore.by_github_login` to use `SharedStrings` instead of
`Strings`. This change was made because user.github_login was cloned in
several areas including the UI, and was cast to a shared string in some
cases too.

C projects with `"` as "brackets" that autoclose, may invoke panics when
edited at the end of the file.

With a single selection-caret (`ˇ`), at the end of the file,
```c
ifndef BAR_H
#define BAR_H

#include <stdbool.h>

int fn_branch(bool do_branch1, bool do_branch2);

#endif // BAR_H
#include"ˇ"
```
gets an LSP response from clangd
```jsonc
{
  "filterText": "AGL/",
  "insertText": "AGL/",
  "insertTextFormat": 1,
  "kind": 17,
  "label": " AGL/",
  "labelDetails": {},
  "score": 0.78725427389144897,
  "sortText": "40b67681AGL/",
  "textEdit": {
    "newText": "AGL/",
    "range": { "end": { "character": 11, "line": 8 }, "start": { "character": 10, "line": 8 } }
  }
}
```

which replaces `"` after the caret (character/column 11, 0-indexed).
This is reasonable, as regular follow-up (proposed in further
completions), is a suffix + a closing `"`:

<img width="842" height="259" alt="image"
src="https://github.com/user-attachments/assets/ea56f621-7008-4ce2-99ba-87344ddf33d2"
/>

Yet when Zed handles user input of `"`, it panics due to multiple
reasons:

* after applying any snippet text edit, Zed did a selection change:
https://github.com/zed-industries/zed/blob/55379876301bd4dcfe054a146b66288d2e60a523/crates/editor/src/editor.rs#L9539-L9545
which caused eventual autoclose region invalidation:
https://github.com/zed-industries/zed/blob/55379876301bd4dcfe054a146b66288d2e60a523/crates/editor/src/editor.rs#L2970

This covers all cases that insert the `include""` text.

* after applying any user input and "plain" text edit, Zed did not
invalidate any autoclose regions at all, relying on the "bracket" (which
includes `"`) autoclose logic to rule edge cases out

* bracket autoclose logic detects previous `"` and considers the new
user input as a valid closure, hence no autoclose region needed.
But there is an autoclose bracket data after the plaintext completion
insertion (`AGL/`) really, and it's not invalidated after `"` handling

* in addition to that, `Anchor::is_valid` method in `text` panicked, and
required `fn try_fragment_id_for_anchor` to handle "pointing at odd,
after the end of the file, offset" cases as `false`

A test reproducing the feedback and 2 fixes added: proper, autoclose
region invalidation call which required the invalidation logic tweaked a
bit, and "superficial", "do not apply bad selections that cause panics"
fix in the editor to be more robust

Release Notes:

- Fixed panic with completion ranges and autoclose regions interop

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

merely using this as a signal to re-fetch the information from Cloud.

Closes #33787

We were not updating SSH paths after initial project was created. Now we
update paths when worktrees are added/removed and serialize these
updated paths. This is separate from workspace because unlike local
paths, SSH paths are not part of the workspace table, but the SSH table
instead. We don't need to update SSH paths every time we serialize the
workspace.
