docs: apply precise fixes for correctness, consistency, and sprintability

Analysis doc improvements:
- Unify runtime naming: fix tree diagram cordova.js → capacitor.js
- Make manifest receivers explicit: add exported attributes and intent filters
- Surface exact-alarm user rule: add decision rule for QA/ops reasoning
- Guard Cordova dependency: add note about Cordova shims requirement
- Add error surfacing to runtime flow: show validation and use-case error paths
- Add auto-generated note to capacitor.plugins.json section

Implementation plan improvements:
- Add diagnostics button to Phase 1 DoD
- Add Doze/Idle case to Test Matrix for false negative prevention
- Make unknown field rejection explicit acceptance criterion
- Link receivers export policy to Manifest Hygiene checklist
- Add event ID requirement to PR checklist for grep-able logs

All changes maintain existing structure with surgical precision edits.
