1.3.0 — Back to the pill

The tetrahedron experiment ends. The HUD is the 1.0.0 capsule again: translucent pill below the notch, live waveform riding your voice, medium-pill + circle cluster for concurrent file jobs. Same sounds as always (Pop / Tink / Blow). Every minimization stays: trimmed menu, one-command CLI, no sessions, silent failure handling, auto-updater, launch at login.
