Rocky a8d58d8f0c feat(polish): allow mood emoji on custom styles and ship Flow/ASR fixes

Custom polish styles can opt in to emotion-matched emoji (default off), with
prompt-level opt-in detection so paste-only styles keep model-added emoji.
Also include Volcengine API-Key ASR auth, voice-processing capture, PiP flash
fix, and related keyboard Shift/haptics reliability work.

Keyboard memory budget — acceptance (OSGDiag)

Phase 0 / 2 memory work is validated on a physical iPhone with Console filtering for OSGDiag. Unit tests and xcodebuild cover compile-time wiring; jetsam behavior is device-only.

Hybrid Flow (product default)

Foreground host is light by default: orphan Live Activity cleanup only — no auto startSession / continuous capture on appear.
Capture starts only on explicit Start / osgkeyboard://startflow / mic press.
Idle background capture is stopped so a parked host does not jetsam the keyboard.
Do not stack CLM + Rime + ASR in the same second after onboarding.
ASR warmup runs on first mic press (beginUtterance), gated by HostMemoryBudget (~260 MB RSS). hostHeavy is set only while heavy work actually runs, then cleared. A sticky hostHeavy (host died mid-work) expires after hostHeavyMaxAge (~120 s) and is cleared on clearFlowState / host-launch reconciliation so typing 中文/EN is not permanently blocked.

Console checklist

Filter Console by process separately: host OSGKeyboard vs extension com.osgkeyboard.ios.keyboard. Host-only filter will never show KVC.*.

Scenario	Expect
Force-quit host, open Notes, switch to OSG	First `dyld.constructor`, then `KVC.init` → `viewDidLoad` → `viewDidAppear`
Host foreground right after launch	`skip capture` + `postOnboardingWarmup scheduled … delay=45s` (no immediate Rime/CLM)
~45 s later, host still active	Serial `rime.installIfNeeded` then `clm.prepare`
First mic press	`scheduleASRWarmup`; `hostHeavy` only while work runs
Switch to typing	Single `rime.prepare` / `englishPrepare`

If neither dyld.constructor nor KVC.init appears after force-quitting the host, the extension is dying in dyld (Shared≈9.4 MB + librime) — next lever is splitting Rime out of Shared.

RSS comparison (optional)

Record OSGDiag rss= tags for:

Cold voice surface only
Cold typing after prepare
Host foreground + extension

Target: typing peak below the old “voice + eager Librime construct” baseline.

Structural split

Extension links OSGKeyboardShared only (no Charts / StoreKit / Speech / HostSupport).
Host embeds OSGKeyboardHostSupport (ASR, CLM, CloudASR, tip/charts UI).
Heavy assets (osg_pinyin.dict.yaml, CLM bin, licenses, local-asr catalog) ship in the host app bundle; extension reads Rime from App Group after deploy.
