v0.6.0

What's Changed

Added

• Task tracking UI: Built complete task management interface with add, edit, delete, and completion toggle functionality.
• Task list state management: Implemented task_list_provider in core/providers for reactive task list and active task selection.
• Active task binding: Timer now displays and binds to selected task, showing task name and tags during focus sessions.
• Task-filtered statistics: Statistics screen now filters sessions by selected task or tag, enabling task-specific productivity insights.
• Task tag support: Tasks can have multiple tags; statistics can be filtered by individual tags.
• CSV export with task data: Exported session data now includes task name and tags columns for external analysis.
• Battery optimization detection: Added BatteryOptimizationService to detect and educate users about Android battery optimization settings.
• Power management service: Implemented PowerManagementService for intelligent wake lock management based on screen state.
• Timer diagnostics logging: Added structured logging for timer events, foreground service actions, and battery-related diagnostics.
• Full session reset button: Added "Start Fresh" button with confirmation dialog to reset all completed cycles and sessions.
• Don't ask again preference: Session reset confirmation can be permanently dismissed via SharedPreferences.
• Comprehensive test suite: Added unit tests for battery optimization, power management, timer controls, statistics screen, and tasks screen.

Changed

• Feature isolation enforcement: Moved task_list_provider from features/tasks to core/providers to maintain architectural boundaries.
• Statistics filter reactivity: Converted statistics filter selector to use StreamProvider for reactive updates.
• Filter mutation API: Simplified statistics filter provider with clearFilters() method and consolidated mutation methods.
• Task modal architecture: Refactored add-task dialog to use StatefulWidget for proper text controller lifecycle management.
• Audio normalization: Implemented per-category LUFS normalization for alarm, ambience, and break audio tracks.
• Database query optimization: Extracted rawSessionsQuery provider to eliminate duplicated joins in statistics and CSV export.

Fixed

• Battery drain: Throttled foreground service updates from every tick to every 5 seconds, reducing IPC calls by ~80%.
• Wake lock retention: Wake locks now released when screen turns off or timer pauses, allowing device deep sleep.
• Foreground service configuration: Reduced notification importance to MIN and callback interval to 1s for battery efficiency.
• Invalid service parameter: Removed non-existent ignoreBatteryOptimization parameter from foreground service init.
• Timer phase reset: Resolved issues with timer phase transitions and database preparation for session logging.
• Statistics filter type safety: Enforced proper type handling in filter selector tasks list to prevent runtime errors.
• CSV export encoding: Added missing dart:typed_data import for proper UTF-8 byte conversion in web exports.
• Mock services setup: Refined mock services configuration and removed unused test dependencies.

Performance

• Foreground service overhead: Reduced battery drain from ~10-15%/hour to <5%/hour during timer sessions.
• CPU wake-ups: Throttled foreground updates reduced context switches between Dart isolate and Android service.
• Statistics query efficiency: Consolidated session queries eliminated redundant database joins.

Docs & Tooling

• Added TESTING.md with comprehensive testing architecture and guidelines.
• Added architecture documentation to TimerNotifier explaining battery efficiency patterns.
• Regenerated Riverpod and Drift generated files for all new providers.
• Updated mock services with PowerManagementService and BatteryOptimizationService mocks.
