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.
