docs(governance): promote audio PoC to PASS; close mobile-Android half

Browse Source 
Documentation update following the Android audio spike pass.

Decision register (v0.9.3 → v0.9.4):
  - DEC-011.1 promoted from
      'Accepted (desktop: cpal) / Deferred (mobile)'
    to
      'Accepted (desktop: cpal; Android: cpal-on-Oboe) / Deferred (iOS)'.
  - Evidence pointer added: poc/audio-capture-playback-android-spike/
    VERIFICATION.md.

PoC plan (v0.2.0 → v0.3.0):
  - Audio row promoted from PARTIAL PASS to PASS.
  - All six PoC plan entries are now PASS.

PoC results summary (v0.1.0 → v0.2.0):
  - Audio row collapsed into one PASS spanning both spikes.
  - RISK-PoC-001 narrowed from 'mobile audio' to 'iOS audio only'.
  - Toolchain table expanded with Android NDK, cargo-ndk, AGP/
    Gradle/Kotlin, jni/ndk-context/android_logger, and the test
    device.

Cross-spike pointers updated:
  - poc/audio-capture-playback-spike/VERIFICATION.md result and
    follow-up sections updated to reference the Android spike.
  - poc/README.md status table lists both audio spike directories.

CHANGELOG updated under [Unreleased].
