v0.5.0 — Ember

### Added

- Integrated terminal in the GUI — footer bar that expands into a resizable bottom panel with tabbed shell sessions via node-pty, Cmd+` toggle, Nerd Font support
- Version display in system tray menu below "Watchfire Daemon" header for easy version identification

### Fixed

- Status indicator dots in sidebar/dashboard now only pulse for projects with an autonomous agent (task, wildfire, start-all) — chat mode no longer triggers pulsing
- Dashboard project card X button overlapping chevron arrow on hover
- GUI crash ("Object has been destroyed") when PTY emits data after BrowserWindow is closed — `onData`/`onExit` callbacks now check `isDestroyed()` before sending IPC messages
