Exercise TUI workflows through the event, update, command, and rendering boundaries using Ratatui’s test backend and snapshots, without invoking external services.

Treat Ctrl+C as an immediate global quit while preserving contextual q/Esc behavior. Ensure tag results leave the introductory state so fetched bookmarks are rendered correctly.

📝 Walkthrough

Walkthrough

The TUI now receives BMM_DEBUG in AppTui::new, handles Ctrl+C with Message::QuitImmediately, and computes terminal-size status from current dimensions. Tag-filtered results update the initial-state flag. A test-only module adds shared TUI helpers and coverage for search, bookmarks, tags, navigation, help, actions, and terminal resizing.

Merge Risk: 🔵 Low · up to 0244f

The TUI now treats control-modified C keys as global quit, but extra modifiers may also exit the application unexpectedly. The change is mergeable with explicit owner awareness or a small follow-up to restrict the shortcut to exact Ctrl+C.
