fix(player): restore native AirPlay after Web Audio capture - #511
Safari can report an AirPlay connection while the visualizer or effects still owns the media element. Detect every captured source and offer a native reload that preserves playback state and stays native across later playback, resizing and reloads.
AirPlay handoff
- captured media → open picker+ captured media → restore native playback → open picker
Control Center handoffs expose the same recovery action without automatically reloading. Explicit local active-effect edits can resume DSP; remote edits, master-off edits and resets retain native mode. Current mobile DSP opt-in, master bypass, presets and VU artwork are preserved.
Evidence
Before: untouched dev (a36666e) failed 15 of the original 20 routing/playback cases. After:npm test passes all 117 tests (73 CJS and 44 TypeScript), including 26 new regressions for native-mode persistence, Control Center recovery, storage failure, one-time playback restoration and advanced master controls.
npx tsc --noEmit --project tsconfig.json, npm run build --ignore-scripts, JavaScript syntax and diff checks pass.
Add PR validation on Node 22 and 24; refresh the player cache to v59.
The reporter confirmed working AirPlay playback after deploying the repair. This dev adaptation was revalidated with the automated checks above; the exact physical device/receiver profile was not recorded.

🎯 核心变更
本次 PR 修复 Web Audio 捕获音频元素后无法直接使用原生 AirPlay 的问题。恢复原生播放时,播放器会替换本地音频元素并尽量恢复播放状态,不需要重载页面;路由切换时会提示用户操作,不会自动恢复或重载。
The change restores native AirPlay playback after audio capture by replacing the media element in place. The earlier concerns about reverb edits pulling playback back into local processing appear to be addressed. No remaining merge-blocking risk was found. Testing used simulated environments rather than a real AirPlay device.

Explanation
Docstring coverage is 6.06% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 33 functions across 9 files. (6 skipped: 5 unsupported, 1 too large.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

📝 主要改动点
playback.js新增LXPlayback.replaceLocalElement(),用于替换本地音频元素、恢复媒体状态,并阻止旧元素事件影响播放器。sound-effects.js增加原生播放优先状态和音频图释放流程。移动端默认使用原生播放;用户显式启用音效或编辑本地音效时,才可切换到本机 DSP。visualizer.js在原生播放优先时使用独立循环,并在音频元素替换后释放旧资源、重新初始化。airplay.js使用needsNativeRestore()判断是否需要恢复;检测到 Control Center 发起的无线投播时,会提示用户恢复原生播放并重新选择设备。
