Use project cwd when opening draft threads without a worktree path

[juliusmarminge]

Summary

• Pass openInCwd from ChatView into ChatHeader/OpenInPicker so editor open actions no longer depend on thread/project lookups inside the picker.
• Prefer activeThread.worktreePath and fall back to activeProject.cwd when computing the open path.
• Update OpenInPicker click/shortcut handlers and button disabled state to use openInCwd directly.
• Add a browser test covering draft-only threads to verify shellOpenInEditor is sent with project cwd when no worktree path exists.

Testing

• Added test: opens the project cwd for draft threads without a worktree path in apps/web/src/components/ChatView.browser.tsx.
• Not run: bun lint.
• Not run: bun typecheck.
• Not run: bun run test.

Note

Medium Risk
Adjusts the path used for native shell.openInEditor actions (button + shortcut) and could change behavior for some thread/project edge cases, though the change is small and covered by a new browser test.

Overview
Ensures the Open in editor action works for local draft threads that don’t yet have a worktreePath by computing an openInCwd in ChatView (worktreePath fallback to project cwd) and passing it down to ChatHeader/OpenInPicker.

OpenInPicker no longer does its own thread/project store lookups; its click handler, keyboard shortcut handler, and disabled state now rely solely on openInCwd.

Adds a browser test that mounts a draft-only thread (no server threads in snapshot), clicks Open, and asserts a shellOpenInEditor WS request is sent with the project cwd (including test harness support to capture WS requests and reset draft store state between tests).

Note

Route Chat header Open control to use the draft thread worktree path or fall back to the project cwd when calling api.shell.openInEditor in ChatView.tsx

Introduce openInCwd in ChatView and pass it through ChatHeader to OpenInPicker, which now calls api.shell.openInEditor with that cwd and disables the control when null; add tests that capture WebSocket RPCs and verify the cwd fallback behavior.

📍Where to Start

Start with ChatView computing openInCwd in ChatView.tsx, then follow its propagation through ChatHeader to OpenInPicker.
