docs: apply surgical corrections for correctness and clarity

Analysis doc improvements:
- Add accuracy note for Capacitor vs Cordova runtime naming
- Declare 5 required Status Matrix fields verbatim in Bridge Surface
- Add Manifest Hygiene checklist to Build Configuration section

Implementation plan improvements:
- Fix BOOT_COMPLETED permission wiring (top-level permissions, not receiver attribute)
- Add user-visible Exact-Alarm Decision Rule for QA/ops reasoning
- Add 2 ops-grade error cases: E_CHANNEL_MISSING, E_BAD_CONFIG
- Add Preflight Golden Path (Demo) to Runbooks for 30-second sanity checks
- Clamp text lengths at JS boundary with unknown field rejection
- Declare minimal Event IDs for deterministic grep operations

All changes maintain existing structure with surgical precision edits.
