The terminal/console titlebar was composed from status marker + model + cwd only; the session's (auto-)title never appeared, even though the TUI already knows it. Change the format to `<marker> <session name> · <model> · <cwd>`, with the session name and cwd each omitted when absent so single-segment titles stay clean. The current session's live title is pulled from the existing session.active_list poll (which already carries each session's current flag and title), so there's no extra round-trip; UiState gains a sessionTitle field updated only when it actually changes, preserving the existing idle-flicker guard. Extract the join logic into a pure composeTabTitle() helper in domain/paths and cover its edge cases (name omitted, cwd omitted, whitespace-only name, marker-only fallback, truncation, boundary length) in paths.test.ts.
