Voice Transcriber v0.5.0 — Daily dictation

Dictate, correct, and intentionally keep or discard text on Linux.\n\nThis release adds an editable transcript desk, bounded undo/redo, per-segment request state, focused push-to-talk, an X11-only capability-gated tray toggle, optional copy-on-final, destination-confirmed plain/Markdown/timestamped exports, and opt-in text-only history with retention and permanent deletion. Raw audio remains non-persistent.\n\nThe x86_64 Flatpak was built and smoke-tested from exact source commit d6770b2 in Actions run 33014228607. Verify the companion SHA-256 file before installing. The bundle requests Wayland, fallback X11/IPC, PulseAudio, and network, without broad filesystem access.\n\nKnown evidence boundary: package/CLI/GTK/accessibility tests passed in automation. A physical Linux microphone, tester-owned Groq key, and five real-participant usability sessions are still explicitly open; this release does not relabel headless checks as that evidence.
