test+diag: SWE.4 unit tests for Rust paths, Dart service tests, diagnostics audio.android section

Verification + diagnostics:

- apps/chanora_flutter/test/services/back_intent_policy_test.dart:
  8-case truth table for the BackIntentPolicy pure function
  (SWE4-UV-042).
- apps/chanora_flutter/test/services/back_intent_service_test.dart:
  5 channel-routing tests (SWE4-UV-042, SWE5-IV-019 unit slice).
- apps/chanora_flutter/test/services/android_permissions_service_test.dart:
  12 tests covering inbound channel events, outbound requests,
  state-machine transitions, and non-Android short-circuit
  (SWE4-UV-041).
- SDD/SRS trace headers added to alpha_e2e_test.dart,
  beta_e2e_test.dart, widget_test.dart so the existing test ↔ ID
  mapping is discoverable by grep.
- chanora_diagnostics: extends DiagnosticExport with android_audio:
  Option<String> for the SDD-116 evidence schema (requested /
  achieved performance mode + sharing mode + input preset + sample
  rate + frames per burst, per-effect engagement, latency tier).
  The bridge's export_diagnostics() now embeds the Android section
  when current_android_audio_diagnostics() returns Some.

All 93 workspace Rust tests and 26 Dart test/services tests pass.
