Airo TV

Stable cut of the `0.0.6` line across Airo TV, the full app, Airo Coins, and
macOS TV. Full notes: [docs/release/AIRO_v0.0.6.md](docs/release/AIRO_v0.0.6.md).

### Added

- Airo Coins is a first-class release-orchestrator leg (`coins_profile`), so the
TV, full, Coins, and macOS artifacts all ship from one reproducible wave
instead of a hand-published Coins upload.
- Offline Meeting Intelligence MVP — record, transcribe, summarise, search.
- Airo Mind Vault phase 1 and the `MindRuntime` port frozen into eight sub-ports.
- Copyable device-capability, runtime-health, and model-advisor diagnostics, plus
chat transcript export.
- Portable shared channel imports for Airo TV.

### Fixed

- Fire TV D-pad focus and BACK paths restored after the #1244 regression.
- TV shell held inside both horizontal and vertical title-safe bands.
- Chess moves are applied instead of silently rejected.
- Playlist source removal is consistent; local media IDs are web-safe.
- Model download queue position, stalled-download recovery, and setup-failure
detail.

### Known issues

- #1240 Airo Coins can open to a persistent black screen on Pixel 9 / Android 17.
- #1430 Airo TV BACK intermittently swallowed on the channel-browse grid.
- #1243 Fire TV live playback emits repeated vendor property-denial log errors.

### Also in this line, since v0.0.6-rc.1

#### Added

- Direct, permission-scoped USB/removable-media browsing on Android TV without
converting local files into playlists, including deterministic sidecar
subtitle association.
- Runtime-backed Xtream live/EPG/VOD and Stalker live source loading, with an
explicit active-source selector and credential-safe failures.
- Reproducible Play Store screenshot capture and RGB/size validation from the
live Flutter web runtime, plus an original text-free feature graphic.
- Production Android signing setup, release provenance attestations, and
repository license/notices preflight coverage.

#### Changed

- The version line is promoted from `0.0.6-rc.1` to `0.0.6` across
`pubspec.yaml`, `pubspec_tv.yaml`, and `pubspec_coins.yaml`, all at build
`+10`.
- TV first-run setup offers URL, expiring phone QR, and USB only when the
corresponding platform capability is real.
- TV rail traversal now has a deterministic leading-edge focus bridge from
Search, Name sort, and the first channel.

#### Fixed

- Coins uses one launcher activity and validates the resolved component before
artifact smoke tests, preventing the Pixel 9 black-screen launch path.
- Player error, loading, buffering, and controls overlays are mutually
exclusive; desktop/macOS hover and fullscreen mini-player transitions are
deterministic.
- Fire TV playback log capture is process-scoped, bounded, classified, and
redacts stream URLs.
- Generated Pigeon/build-runner outputs and model warmup/activation boundaries
compile and carry focused test coverage.

#### Qualification status

- Automated source, player, TV navigation, legal, provenance, native-media,
screenshot, and artifact checks run in CI on every release wave.
- Pixel 9, Fire TV Stick, and iPad physical-device sign-off was not repeated for
this cut; the known issues above are the outstanding device-verified defects.
