docs: add operational sections to Android app analysis and implementation plan

- Add 5 surgical sections to android-app-analysis.md:
  * Assumptions & Versions table (Android SDK, Capacitor, WorkManager, Room, Exact Alarms)
  * Bridge Surface summary with method I/O shapes
  * Permission & Settings Truth Table (symptoms → actions)
  * Runtime Flow Diagram (mermaid)
  * Cordova vs Capacitor assets accuracy note

- Add 6 execution rails to android-app-improvement-plan.md:
  * Phase DoD blocks for PR gating
  * RACI for multi-contributor PRs
  * PR Checklist template
  * Test Matrix from scenarios
  * Error Code Canon table
  * Operational Runbooks stubs

- Fix accuracy: correct 'cordova.js' references to 'capacitor.js'
- Make Status Matrix required fields explicit (5 specific fields)
- Keep existing structure intact, minimal churn approach

 The integration between the web assets (`/www`) and native Android code through Capacitor's bridge system creates a seamless testing environment that allows developers to validate plugin functionality in real-time while providing an intuitive interface for non-technical users to test and understand the plugin's capabilities.
 
 This architecture serves as both a practical testing tool and a reference implementation for integrating the DailyNotification plugin into other applications.

+## Assumptions & Versions
+
+| Topic | Value | Notes |
+|---|---|---|
+| Android min/target SDK | 24 / 35 | Align with `compileSdkVersion`/`targetSdkVersion`. |
+| Capacitor | v5.x | Confirm web asset naming (`capacitor.js` vs Cordova shims). |
+| WorkManager | 2.9.0 | Matches Gradle deps listed. |
+| Room | 2.6.1 | Matches Gradle deps listed. |
+| Exact Alarms | Tiramisu+ | Requires user grant on many OEMs. |

+- `checkPermissionStatus() -> {postNotificationsGranted, exactAlarmGranted, batteryOptIgnored, channelEnabled, ...}`
+- `openChannelSettings() -> {opened: boolean}`
+- `openExactAlarmSettings() -> {opened: boolean}`
+- `requestNotificationPermissions() -> {granted: boolean, permissions: {...}}`
+- `getNotificationStatus() -> {isEnabled, isScheduled, nextNotificationTime, ...}`
+
+## Permission & Settings Truth Table
+
+| Symptom | Likely Cause | Action |
+|---|---|---|
+| No notification posts | `POST_NOTIFICATIONS` denied | Call `requestNotificationPermissions()` |
+| Fires late/misses | No exact alarm grant / Doze | `openExactAlarmSettings()` or fallback to WorkManager |
+| Silent notifications | Channel disabled/low importance | `openChannelSettings()` then retest |
+| Battery optimization kills | App not whitelisted | Guide user to battery optimization settings |
+| Boot reschedule fails | `RECEIVE_BOOT_COMPLETED` denied | Check manifest receiver registration |

+## Cordova vs Capacitor Assets – Accuracy Note
+
+> **Note:** If using pure Capacitor v5, the web runtime is `capacitor.js`. If Cordova compatibility is enabled, `cordova.js/cordova_plugins.js` will appear; otherwise remove those references here for accuracy.
