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
+Refactor plugin methods that validate input then delegate to services:
-- Added SCHEMA_VERSION constant and checkSchemaVersion() method in PersistenceController
+- requestNotificationPermissions() → PermissionManager
-- Version stored in NSPersistentStore metadata (observability contract, not migration gate)
+- openChannelSettings() → ChannelManager  
-- CoreData auto-migration remains authoritative; version mismatches logged, not blocked
+- createSchedule/updateSchedule/deleteSchedule/enableSchedule() → ScheduleHelper
-- Documentation added to ios/Plugin/README.md with migration contract
+- 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
+Enhanced services:
-- Added 3 resilience test scenarios to DailyNotificationRecoveryTests.swift:
+- PermissionManager: Added checkExactAlarmPermission() and requestExactAlarmPermission()
-  - test_combined_dst_boundary_duplicate_delivery_cold_start()
+- ChannelManager: Enhanced openChannelSettings() with channelId parameter and fallback logic
-  - test_combined_rollover_duplicate_delivery_cold_start()
+- ScheduleHelper: Added disableAllSchedulesByKind() method
-  - test_combined_schema_version_cold_start_recovery()
+- DailyNotificationScheduler: Added testAlarm() wrapper method
-- All tests labeled with @resilience @combined-scenarios comments
-- Tests verify idempotency and correctness under combined stressors
 
-P2.3: Android Combined Tests Design
+Reduces plugin class complexity by ~200 lines.
-- Created P2.3-DESIGN.md with scope, invariants, and acceptance criteria
+Services already exist - this is delegation, not extraction.
-- 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.

+   - **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)

+     - 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)
