Migrate keyboard dictation to continuous Flow sessions with auto-start,
tap-to-toggle recording, 60s countdown, five-step onboarding, and App Group
IPC. Add docs/ GitHub Pages site with en/zh privacy policy for App Store compliance.
1) Preview chips weren't actually buttons.
`modeChip` and `localeChip` in `KeyboardPreviewStub` were
decorative HStacks — no `Button`, no action, no callback. The
chevron-down glyph made them *look* like pickers, so a user
tapping them got nothing. The screenshot the user shared
("润色 ▾" / "中文(简体) ▾") shows exactly that surface.
Fix: wrap each chip in a `Button(action: ...)` with
`.buttonStyle(.plain)`. The stub now takes `modeId`, `localeId`,
`onModeCycle`, `onLocaleCycle` and the sheet's `cycleMode` /
`cycleLocale` advance the config:
- mode cycles [off → transcribe → polish] (mirrors Settings)
- locale cycles [auto → zh-Hans → zh-Hant → en-US → ja-JP → ko-KR]
Mid-recording locale switches call `asr.stop()` because ASR
sessions are bound to the locale they were started with.
`modeId == "off"` also stops any in-flight recording so the
disc isn't recording into a mode that won't insert.
The mode chip's icon also follows the mode (mic.slash /
mic / wand) as a redundant visual cue, and both chips get
accessibility labels (preview.modeChip.cycle /
preview.localeChip.cycle) so VoiceOver users can use them.
2) Onboarding's "Next" stays enabled when local engine is picked
but no API key is filled in. Root cause: `ProviderConfig.isConfigured`
checks `!apiKey.isEmpty && !baseURL.isEmpty && !model.isEmpty` —
it never asks whether the user *needs* a key. The local engine
(on-device ASR) doesn't round-trip through the LLM, so an
empty key on the local path is correct, not a configuration gap.
Fix: short-circuit `isConfigured` to `true` when
`engineMode == "local"`. The onboarding "Next" button is
already disabled on the API page when `!isConfigured`; this
just makes the gate respect the engine choice. New test
`testIsConfiguredTrueForLocalEngineWithoutAPIKey` locks the
behaviour in (local → true, cloud → false, flip back).
3) Add the two new accessibility keys to all four
`Localizable.strings` files (en + zh-Hans, main app + ext)
so VoiceOver and the cycle button labels resolve in both
languages.
Build: BUILD SUCCEEDED.
Tests: 22/22 pass (1 new).
