omni-dev 0.43.0

//! Local, daemon-free "a tab of mine is open on this worktree" tracking.
//!
//! Computed purely from this process's own terminal tabs (wired up when a
//! later phase adds embedded PTYs) — never a daemon round-trip, since the TUI
//! does not register itself as a window with the worktrees registry (issue
//! #1585 §7: registering would make the daemon's `open`/`reposition` actions
//! — which assume a VS Code window — target a TUI pane that has neither a
//! `code` process to launch nor an `NSWindow` to reposition).
