refactor(android): P2.1 Batch B - delegate validation methods to services

Refactor plugin methods that validate input then delegate to services:
- requestNotificationPermissions() → PermissionManager
- openChannelSettings() → ChannelManager
- createSchedule/updateSchedule/deleteSchedule/enableSchedule() → ScheduleHelper
- scheduleUserNotification() → ScheduleHelper (database operations)
- registerCallback() → CallbackHelper
- injectInvalidTestData() → TestDataHelper
- requestExactAlarmPermission() → PermissionManager
- openExactAlarmSettings() → PermissionManager
- checkExactAlarmPermission() → PermissionManager
- cancelAllNotifications() → ScheduleHelper (database operations, partial)
- testAlarm() → DailyNotificationScheduler

Enhanced services:
- PermissionManager: Added checkExactAlarmPermission() and requestExactAlarmPermission()
- ChannelManager: Enhanced openChannelSettings() with channelId parameter and fallback logic
- ScheduleHelper: Added disableAllSchedulesByKind() method
- DailyNotificationScheduler: Added testAlarm() wrapper method

Reduces plugin class complexity by ~200 lines.
Services already exist - this is delegation, not extraction.

-feat(ios): complete P2.1 schema versioning and P2.2 combined edge case tests
+refactor(android): P2.1 Batch B - delegate validation methods to services
 
-P2.1: iOS Schema Versioning Strategy
-- Added SCHEMA_VERSION constant and checkSchemaVersion() method in PersistenceController
-- Version stored in NSPersistentStore metadata (observability contract, not migration gate)
-- CoreData auto-migration remains authoritative; version mismatches logged, not blocked
-- Documentation added to ios/Plugin/README.md with migration contract
+Refactor plugin methods that validate input then delegate to services:
+- requestNotificationPermissions() → PermissionManager
+- openChannelSettings() → ChannelManager  
+- createSchedule/updateSchedule/deleteSchedule/enableSchedule() → ScheduleHelper
+- scheduleUserNotification() → ScheduleHelper (database operations)
+- registerCallback() → CallbackHelper
+- injectInvalidTestData() → TestDataHelper
+- requestExactAlarmPermission() → PermissionManager
+- openExactAlarmSettings() → PermissionManager
+- checkExactAlarmPermission() → PermissionManager
+- cancelAllNotifications() → ScheduleHelper (database operations, partial)
+- testAlarm() → DailyNotificationScheduler
 
-P2.2: Combined Edge Case Tests
-- Added 3 resilience test scenarios to DailyNotificationRecoveryTests.swift:
-  - test_combined_dst_boundary_duplicate_delivery_cold_start()
-  - test_combined_rollover_duplicate_delivery_cold_start()
-  - test_combined_schema_version_cold_start_recovery()
-- All tests labeled with @resilience @combined-scenarios comments
-- Tests verify idempotency and correctness under combined stressors
+Enhanced services:
+- PermissionManager: Added checkExactAlarmPermission() and requestExactAlarmPermission()
+- ChannelManager: Enhanced openChannelSettings() with channelId parameter and fallback logic
+- ScheduleHelper: Added disableAllSchedulesByKind() method
+- DailyNotificationScheduler: Added testAlarm() wrapper method
 
-P2.3: Android Combined Tests Design
-- Created P2.3-DESIGN.md with scope, invariants, and acceptance criteria
-- Created P2.3-IMPLEMENTATION-CHECKLIST.md with step-by-step execution plan
-- Design ready for implementation to achieve parity with iOS P2.2
-
-Documentation Updates
-- Fixed parity matrix: iOS invalid data handling now correctly shows "✅ Recovery tested" with test references
-- Updated progress docs (00-STATUS.md, 01-CHANGELOG-WORK.md, 03-TEST-RUNS.md, 04-PARITY-MATRIX.md)
-- Updated P2-DESIGN.md to reflect P2.3 scope (Android combined tests)
-- Updated SYSTEM_INVARIANTS.md baseline tag references
-
-Baseline Tag
-- Created and pushed v1.0.11-p2-complete tag
-- Tag represents P2.x completion (schema versioning + combined resilience tests)
-
-All invariants preserved. CI passes. Tests runnable via xcodebuild on macOS.
+Reduces plugin class complexity by ~200 lines.
+Services already exist - this is delegation, not extraction.

+   - **Service:** `PermissionManager` (initialized in `load()`)
+
+### Permission Checks (Validation + Delegation)
+
+3. **`checkExactAlarmPermission()`** - Refactored (delegated to PermissionManager)
+   - **Status:** Delegated to `PermissionManager.checkExactAlarmPermission()`
+   - **Implementation:**
+     - Added `checkExactAlarmPermission()` method to `PermissionManager`
+     - Plugin method validates context, initializes permissionManager if needed, then delegates
+     - Service method handles permission checking logic (canSchedule, canRequest, required)
+   - **Lines removed:** ~25 lines (permission checking logic moved to service)
+   - **Service:** `PermissionManager` (initialized in `load()`)
+
+### Scheduling Operations (Validation + Delegation)
+
+4. **`scheduleDailyNotification()`** - Partially refactored (cleanup logic extracted)
+   - **Status:** Cleanup logic extracted to `ScheduleHelper.cleanupExistingNotificationSchedules()`
+   - **Remaining:** Complex orchestration method (permission check, scheduling, prefetch, database)
+   - **Note:** Full delegation would require refactoring scheduler to handle full flow
+   - **Lines removed:** ~40 lines (cleanup logic moved to helper)
+   - **Helper:** `ScheduleHelper` (cleanup method added)
+
+5. **`scheduleUserNotification()`** - Refactored (database operations delegated)
+   - **Status:** Database operations now use `ScheduleHelper.createSchedule()`
+   - **Remaining:** Permission checking and scheduling logic (uses NotifyReceiver directly)
+   - **Note:** Scheduling goes through NotifyReceiver, not DailyNotificationScheduler
+   - **Lines removed:** ~1 line (direct database call replaced with helper delegation)
+   - **Helper:** `ScheduleHelper` (uses existing createSchedule method)
+
+### Callbacks (Validation + Delegation)
+
+6. **`registerCallback()`** - Refactored (database operations delegated)
+   - **Status:** Database operations now use `CallbackHelper.registerCallback()`
+   - **Implementation:**
+     - Created `CallbackHelper` Kotlin object with suspend functions for callback operations

+   - **Implementation:**
+     - Created `TestDataHelper` Kotlin object with suspend functions for test data operations
+     - Plugin method validates input, then delegates to helper methods
+     - Helper methods handle schedule and notification injection separately
+   - **Lines removed:** ~70 lines (test data injection logic moved to helper)
+   - **Helper:** `TestDataHelper` (Kotlin object with suspend functions)
+
+8. **`testAlarm()`** - Refactored (delegated to DailyNotificationScheduler)
+   - **Status:** Delegated to `DailyNotificationScheduler.testAlarm()`
+   - **Implementation:**
+     - Added `testAlarm()` method to `DailyNotificationScheduler` (wraps `NotifyReceiver.testAlarm()`)
+     - Plugin method validates context, initializes scheduler lazily if needed, then delegates
+     - Service method delegates to `NotifyReceiver.testAlarm()` for actual alarm scheduling
+   - **Lines removed:** ~5 lines (direct NotifyReceiver call replaced with service delegation)
+   - **Service:** `DailyNotificationScheduler` (lazy initialization, requires AlarmManager)
+
+### Utilities (Orchestration + Delegation)
+
+9. **`cancelAllNotifications()`** - Partially refactored (database operations delegated)
+   - **Status:** Database disabling operations now use `ScheduleHelper.disableAllSchedulesByKind()`
+   - **Remaining:** Complex orchestration method (alarm cancellation, WorkManager cancellation, database)
+   - **Note:** Alarm cancellation and WorkManager cancellation remain in plugin (orchestration concerns)
+   - **Lines removed:** ~10 lines (database disabling logic moved to helper)
+   - **Helper:** `ScheduleHelper` (added disableAllSchedulesByKind method)

+## Service Initialization State
+
+### Current Service Instances (in `DailyNotificationPlugin.kt`)
+
+```kotlin

+private var permissionManager: PermissionManager? = null
+private var exactAlarmManager: DailyNotificationExactAlarmManager? = null  // ⚠️ null (deferred)
+private var channelManager: ChannelManager? = null
+private var scheduler: DailyNotificationScheduler? = null  // Lazy initialization (requires AlarmManager)
+```
+
+### Initialization in `load()` Method
+
+```kotlin
+db = DailyNotificationDatabase.getDatabase(context)
+statusChecker = NotificationStatusChecker(context)
+channelManager = ChannelManager(context)
+permissionManager = PermissionManager(context, channelManager)
