docs(p0): SysRS/SysDes/SRS/SAD/SDD/Verification + traceability for Android P0 reconciliation

Browse Source 
Full P0 Android documentation chain:

- SysRS: API 24 → API 28 reconciliation per DEC-004 (SysRS-288);
  add SysRS-305 (Android in-call audio mode), SysRS-306
  (RECORD_AUDIO runtime timing).
- SysDes: SysDes-152 (in-call audio mode subsystem), SysDes-153
  (RECORD_AUDIO permission flow), SysDes-154 (Android voice audio
  backend), SysDes-155 (macOS runtime baseline).
- SRS: SRS-187 → API 28; add SRS-208 (in-call audio mode), SRS-209
  (RECORD_AUDIO + listen-only fallback), SRS-210..215 (Android voice
  audio backend latency/preset/AEC/usage/sharing/foreground service);
  retarget SysDes anchors from generic SysDes-135 to SysDes-152/153/154.
- SAD: SAD-063 refreshed (API 28); add SAD-084 (audio mode
  controller), SAD-085 (permission adapter with listen-only),
  SAD-086 (foreground service), SAD-087 (macOS runtime baseline);
  formalize cross-cutting + platform-specific allocation pattern
  in §24.1.
- SDD: expand SDD-028 (BackIntentService); refresh SDD-073 (build
  config); add SDD-105 (JNI bootstrap), SDD-106 (permission
  requester), SDD-107 (foreground service), SDD-108 (audio mode
  controller), SDD-109 (AAB pipeline), SDD-110 (PTT capability),
  SDD-111..116 (Android voice audio backend), SDD-118 (Android
  bridge build automation), SDD-119 (iOS/macOS bridge build
  automation back-fill).
- Verification: create android-p0-acceptance.md TC-1..TC-18; add
  SWE4-UV-040..052, SWE5-IV-016..026, SWE6-SV-018..030,
  SYS4-SIV-015 strengthened + SYS4-SIV-017/018.
- Governance: traceability matrix v0.9.9 with end-to-end chain
  closure; DEC-032 documents the temporary abiFilters reduction to
  arm64-v8a only and its restore-by gate.

Trace: full chain SysRS → SysDes → SRS → SAD → SDD → Code → Verification.
