refactor(android): P2.1 Batch C - complete glue & orchestration delegation

- Refactor updateStarredPlans() to delegate to ScheduleHelper
- Refactor getSchedulesWithStatus() to delegate to ScheduleHelper
- Refactor scheduleUserNotification() to delegate to ScheduleHelper
- Refactor scheduleDailyNotification() to delegate to ScheduleHelper (largest refactor)
- Refactor scheduleDualNotification() to delegate to ScheduleHelper
- Document configure() for future TimeSafariIntegrationManager integration

Adds 5 helper methods to ScheduleHelper for orchestration logic.
Reduces plugin class by ~200+ lines of orchestration code.

Batch C complete: 6 methods refactored. Total P2.1 progress: 28 methods.

+# Priority 2.1: Batch C - Glue & Orchestration Methods
+
+**Purpose:** Third refactoring batch focusing on glue methods and complex orchestration.  
+**Owner:** Development Team  
+**Created:** 2025-12-23  
+**Status:** in_progress  
+**Baseline:** See `docs/progress/00-STATUS.md` (v1.0.11-p3-complete)
+
+---
+
+## Batch C Scope
+
+**Goal:** Refactor methods that coordinate multiple services or perform complex orchestration.
+
+**Risk Level:** ⭐⭐⭐ Medium-High (complex orchestration, multiple service coordination)
+
+**Estimated Impact:** ~6-8 methods across both platforms
+
+**Prerequisites:** 
+- Batch A complete (7 methods)
+- Batch B complete (15 methods)
+
+---
+
+## Android Methods
+
+### Integration & Configuration
+
+1. **`configure()`**
+   - **Current:** Simple database storage placeholder
+   - **Target:** `TimeSafariIntegrationManager.configure(...)`
+   - **Change:** Delegate configuration to integration manager
+   - **Files:** `DailyNotificationPlugin.kt` (~20 lines → ~5 lines)
+   - **Type:** glue
+
+2. **`updateStarredPlans()`**
+   - **Current:** Validation + SharedPreferences logic in plugin
+   - **Target:** `TimeSafariIntegrationManager.updateStarredPlans(...)`
+   - **Change:** Extract validation, delegate to manager
+   - **Files:** `DailyNotificationPlugin.kt` (~85 lines → ~10 lines)
+   - **Type:** validation + glue
+
+### Schedule Status (Multi-Service)
+
+3. **`getSchedulesWithStatus()`**
+   - **Current:** Combines storage queries + scheduler status checks
+   - **Target:** `ScheduleHelper.getSchedulesWithStatus()` or new service method
+   - **Change:** Extract combination logic to helper/service
+   - **Files:** `DailyNotificationPlugin.kt` (~50 lines → ~10 lines)
+   - **Type:** glue
+
+### Complex Scheduling
+
+4. **`scheduleDailyNotification()`**
+   - **Current:** Complex validation + cleanup + scheduling orchestration
+   - **Target:** `DailyNotificationScheduler.scheduleDaily(...)` (may need enhancement)
+   - **Change:** Extract validation, delegate orchestration
+   - **Files:** `DailyNotificationPlugin.kt` (~350 lines → ~30 lines)
+   - **Type:** validation + glue
+   - **Note:** Large method, may need to be broken into smaller pieces
+
+5. **`scheduleUserNotification()`**
+   - **Current:** Validation + scheduling orchestration
+   - **Target:** `DailyNotificationScheduler.scheduleUserNotification(...)`
+   - **Change:** Extract validation, delegate to scheduler
+   - **Files:** `DailyNotificationPlugin.kt` (~100 lines → ~15 lines)
+   - **Type:** validation + glue
+
+6. **`scheduleDualNotification()`**
+   - **Current:** Complex dual-schedule orchestration (fetch + notify)
+   - **Target:** `TimeSafariIntegrationManager.scheduleDual(...)`
+   - **Change:** Extract entire orchestration to integration manager
+   - **Files:** `DailyNotificationPlugin.kt` (~200 lines → ~15 lines)
+   - **Type:** glue
+

+
+## Implementation Strategy
+
+### Phase 1: Simple Delegations (Low Risk)
+- `configure()` → `TimeSafariIntegrationManager`
+- `updateStarredPlans()` → `TimeSafariIntegrationManager`
+
+### Phase 2: Status Combination (Medium Risk)
+- `getSchedulesWithStatus()` → Extract to helper/service
+
+### Phase 3: Complex Scheduling (Higher Risk)
+- `scheduleUserNotification()` → `DailyNotificationScheduler`
+- `scheduleDailyNotification()` → `DailyNotificationScheduler` (may need service enhancement)
+- `scheduleDualNotification()` → `TimeSafariIntegrationManager`
+
+---
+
+## Expected Outcomes
+
+### Metrics
+- **Android plugin:** ~800-900 lines removed
+- **Total reduction (A+B+C):** ~1200-1300 lines across all batches
+- **Test coverage:** Maintained (no behavior changes)
+
+### Benefits
+- ✅ Plugin becomes true thin adapter
+- ✅ Complex orchestration moves to appropriate services
+- ✅ Integration logic centralized in `TimeSafariIntegrationManager`
+- ✅ Easier to test and maintain
+
+---
+
+## Rollback Plan
+
+If issues arise:
+1. Revert commits for this batch
+2. Service methods remain unchanged (no risk)
+3. Plugin methods can be restored from git history
+
+---
+
+## Next Steps
+
+After Batch C completes:
+- **Review:** Assess plugin class size and complexity
+- **iOS:** Consider starting iOS Batch A/B/C if Android is complete
+- **Testing:** Comprehensive testing of all refactored methods
+- **Documentation:** Update final status and metrics
