refactor(android): P2.1 Batch A - delegate 7 plugin methods to services

P2.1 Batch A: Pure delegation refactoring (low-risk, read-only operations) Completed Refactorings: - checkStatus() → NotificationStatusChecker.getComprehensiveStatus() - getNotificationStatus() → NotificationStatusChecker + NotificationStatusHelper - checkPermissionStatus() → PermissionManager.checkPermissionStatus() - isChannelEnabled() → ChannelManager methods - isAlarmScheduled() → DailyNotificationScheduler.isScheduled() - getNextAlarmTime() → DailyNotificationScheduler.getNextAlarmTime() - getContentCache() → ContentCacheHelper.getLatest() Service Enhancements: - Added NotificationStatusChecker.getNotificationStatus() (delegates to helper) - Added DailyNotificationScheduler.isScheduled() (wraps NotifyReceiver) - Added DailyNotificationScheduler.getNextAlarmTime() (wraps NotifyReceiver) Helper Objects Created: - NotificationStatusHelper: Kotlin object for notification status queries - ContentCacheHelper: Kotlin object for content cache operations Code Reduction: - ~181 lines removed from DailyNotificationPlugin.kt - Logic moved to service layer (better separation of concerns) - Plugin class now acts as thin adapter layer Deferred: - getExactAlarmStatus() (requires complex service initialization) All methods maintain same API behavior. Plugin class complexity reduced. Services already existed - this is delegation, not extraction. Refs: docs/progress/P2.1-BATCH-A-STATE.md

 **Phase:** P2.1 - Native Plugin Refactoring (Batch A)  
 **Goal:** Refactor plugin methods to delegate to existing services (thin adapter pattern)  
-**Status:** 3 of ~10 methods completed, 1 deferred
+**Status:** ✅ **BATCH A COMPLETE** — 7 methods refactored, 1 deferred

 ---

 ## Completed Refactorings

 ### ✅ Android: `checkStatus()`
+
 - **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
 - **Change:** Delegated to `NotificationStatusChecker.getComprehensiveStatus()`
 - **Lines removed:** ~50 lines
 - **Service:** `NotificationStatusChecker` (initialized in `load()`)

 ### ✅ Android: `getNotificationStatus()`
+
 - **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
 - **Change:** Delegated to `NotificationStatusChecker.getNotificationStatus()`
- **Lines removed:** ~35 lines
+- **Implementation:** 
+  - Plugin method delegates to `NotificationStatusChecker.getNotificationStatus(database)`
+  - Java method calls `NotificationStatusHelper.getNotificationStatusBlocking()` (Kotlin helper)
+  - Helper function handles suspend database operations using coroutines
+- **Lines removed:** ~35 lines (logic moved to helper)
 - **Service:** `NotificationStatusChecker` (initialized in `load()`)
+- **Helper:** `NotificationStatusHelper` (Kotlin object with suspend function + Java-compatible blocking wrapper)

 ### ✅ Android: `checkPermissionStatus()`
+
 - **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
 - **Change:** Delegated to `PermissionManager.checkPermissionStatus(call)`
 - **Lines removed:** ~47 lines
 - **Service:** `PermissionManager` (initialized in `load()` with `ChannelManager` dependency)

+### ✅ Android: `isChannelEnabled()`
+
+- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
+- **Change:** Delegated to `ChannelManager` methods
+- **Implementation:**
+  - Uses `channelManager.ensureChannelExists()` to ensure channel exists
+  - Uses `channelManager.isChannelEnabled()` for channel enabled check
+  - Uses `channelManager.getChannelImportance()` for importance level
+  - Uses `channelManager.getDefaultChannelId()` for channel ID
+  - Keeps app-level notification check in plugin (appropriate for plugin layer)
+- **Lines removed:** ~37 lines (channel creation/checking logic moved to service)
+- **Service:** `ChannelManager` (initialized in `load()`)
+
+### ✅ Android: `isAlarmScheduled()`
+
+- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
+- **Change:** Delegated to `DailyNotificationScheduler.isScheduled()`
+- **Implementation:**
+  - Added `isScheduled()` method to `DailyNotificationScheduler` (wraps `NotifyReceiver.isAlarmScheduled()`)
+  - Plugin method initializes scheduler lazily (requires AlarmManager)
+  - Delegates to `scheduler.isScheduled(triggerAtMillis)`
+  - Service method checks actual AlarmManager state via PendingIntent
+- **Lines removed:** ~5 lines (direct NotifyReceiver call replaced with service delegation)
+- **Service:** `DailyNotificationScheduler` (lazy initialization, requires AlarmManager)
+
+### ✅ Android: `getNextAlarmTime()`
+
+- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
+- **Change:** Delegated to `DailyNotificationScheduler.getNextAlarmTime()`
+- **Implementation:**
+  - Added `getNextAlarmTime()` method to `DailyNotificationScheduler` (wraps `NotifyReceiver.getNextAlarmTime()`)
+  - Plugin method initializes scheduler lazily (requires AlarmManager)
+  - Delegates to `scheduler.getNextAlarmTime()`
+  - Service method gets actual AlarmManager next alarm clock
+- **Lines removed:** ~5 lines (direct NotifyReceiver call replaced with service delegation)
+- **Service:** `DailyNotificationScheduler` (lazy initialization, requires AlarmManager)
+
+### ✅ Android: `getContentCache()`
+
+- **File:** `android/src/main/java/com/timesafari/dailynotification/DailyNotificationPlugin.kt`
+- **Change:** Delegated to `ContentCacheHelper.getLatest()`
+- **Implementation:**
+  - Created `ContentCacheHelper` Kotlin object with suspend function for database operations
+  - Plugin method delegates to `ContentCacheHelper.getLatest(database)`
+  - Helper function handles suspend database operations using coroutines
+  - Maintains same API behavior (returns latest ContentCache entry)
+- **Lines removed:** ~2 lines (direct database call replaced with helper delegation)
+- **Helper:** `ContentCacheHelper` (Kotlin object with suspend function, similar to NotificationStatusHelper)
+

 - Initialize `DailyNotificationStorage` (may already exist via database)
 - Create factory method for `DailyNotificationExactAlarmManager` initialization
