- Refactor frontend terminal from single shared instance to per-instance sessions, each owning its own xterm.js instance, transport state, timers, and reconnect logic. - Switching between running instances now hides inactive terminal containers instead of tearing down their PTY attachment, preventing disruption of long-lived TUI programs like Copilot CLI. - Add session lifecycle management: createTerminalSession, destroyTerminalSession, maybeDestroyInactiveStoppedSession, reconcileTerminalSessions, reconnectRunningTerminalSessions. - Add reportSessionError for unified per-session error handling. - Update docs/API.md, docs/ARCHITECTURE.md, and docs/PRD.md to document the new frontend session model and instance switch protocol. - Add comprehensive tests covering multi-instance switching, session lifecycle, reconcile logic, and per-session connection management.

- List() now queries current branch for each worktree via git rev-parse - GitCommand() helper in gitx package centralizes timeout-protected git execution - currentBranch() returns (string, error) to distinguish errors from empty values - On error (path gone, detached HEAD), List() keeps stored Branch value - All git commands now have WaitDelay timeouts (2s/5s/10s based on operation) - Docs updated: API.md, ARCHITECTURE.md, CLAUDE.md clarify 'branch' is live value - Main Workspace support documented for running instances in main repo Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>
Backend:
- Add ErrInstanceNotFound variable for proper error handling
- Add UpdateName() method to instance.Manager, return updated instance
- Add PATCH /api/instances endpoint with {id, name} body
- Use errors.Is() for error classification
Frontend:
- Double-click instance tab to rename inline
- Skip refresh() render during rename to preserve IME composition
- Commit rename on Enter, cancel on Escape
- Protect focus from terminal during rename
- Simplify state management
Docs:
- Update API.md with Rename endpoint spec
- Update ARCHITECTURE.md and CLAUDE.md
Tests:
- Add TestHandleInstanceUpdate covering 200/400/404 cases

Implements drag-and-drop tab reordering for instances with optimistic locking to prevent data loss from concurrent modifications. Key changes: - State.Version: monotonically increasing version for conflict detection - SaveWithVersion: atomic save with version check (returns ErrVersionConflict) - PATCH /api/instances/reorder: reorder tabs with version validation - Frontend: HTML5 drag-and-drop + rollback on HTTP 409 Conflict - Comprehensive concurrent tests covering race conditions (reorder vs start) The frontend tracks version from GET /api/instances and sends it back on reorder. If state changed (e.g., another user started an instance), server returns 409 and client rolls back UI to last confirmed order before refreshing. All instance write operations (Start/Stop/Rename/Reorder/etc.) now use SaveWithVersion. Legacy state.json (no version field) migrates smoothly.
