* fix: simple timer restart after 15 minutes

Android checks every 15 minutes if service is alive with an intent whose action is null. MainActivity now starts FocusModeService with the ACTION_START intent action. FocusModeService handles ACTION_START explicitly in onStartCommand, improving intent handling and service control.

* Only promote to foreground if not pausing timer

Updated onStartCommand to call promoteToForeground only when the intent action is not ACTION_PAUSE, preventing unnecessary foreground promotion when pausing the timer.

Removes unnecessary stopSelf that killed the timer on null actions.

Introduces a comprehensive system for tracking, persistence, and visualization of focus sessions (Simple and Pomodoro).

Key changes include:
*   **Focus Stats System**:
    *   Implemented `FocusStats` utility to manage session lifecycles, phase transitions, and app block event recording.
    *   Added data models for `FocusSession`, `PhaseEntry`, and `BlockEvent` with JSON serialization for persistence.
    *   Integrated session tracking into `FocusModeService` to record actual duration and completion status.
*   **New UI Screens**:
    *   **FocusStatsScreen**: Provides daily, weekly, and monthly overviews of focus time and session frequency using interactive charts.
    *   **FocusSessionDetailScreen**: Detailed breakdown of individual sessions, including phase-specific metrics and a list of blocked app attempts with timestamps.
*   **Developer Tools**: Added options in Settings to generate 3 months of sample data for testing and a feature to clear all recorded focus data.
*   **Visualization Enhancements**:
    *   Introduced `TimeLineChart` for trend visualization.
    *   Updated `TimeColumnChart` with improved styling and Material 3 expressive shapes.
    *   Migrated Vico charting library imports to the Compose-specific package.
*   **Infrastructure**:
    *   Added navigation routes for stats and session details.
    *   Registered `routineChangeReceiver` using `ContextCompat` for better cross-version compatibility.
    *   Bumped Gradle to `9.4.0-rc-1`, AGP to `9.2.0-alpha02`, and Kotlin to `2.3.10`.
    *   Updated several library dependencies including Compose BOM, Material3, and Vico.

This commit introduces a more detailed and interactive notification system for focus sessions, especially for Pomodoro mode, and transitions the app to a more modern Material 3 layout with improved scrolling behavior.

Key changes include:
*   **Enhanced Notifications**:
    *   Implemented `ProgressStyle` for notifications, providing a visual breakdown of Pomodoro cycles (focus vs. break segments) on supported Android versions.
    *   Updated the notification icon to a themed hourglass and added a short critical text chip for time remaining.
    *   Improved progress calculation to account for cumulative time across Pomodoro phases.
*   **UI Modernization**:
    *   Transitioned multiple screens (`FocusStats`, `Timer`, `AppUsage`, `Routines`, `Settings`) to use `LargeTopAppBar` with `exitUntilCollapsed` scroll behavior and `nestedScroll` integration.
    *   Refactored `MainActivity` and `TimerScreen` to better handle layout insets and scrolling contexts.
    *   Refined the `MainSettingsScreen` by removing the redundant donate button and adjusting spacing.
*   **Permission Updates**:
    *   Added `WAKE_LOCK` and `USE_EXACT_ALARM` permissions to `AndroidManifest.xml` to improve background reliability and routine scheduling.
    *   Updated the onboarding flow to explicitly request "Do Not Disturb" access on Android 13+.
*   **Assets**: Updated launcher icons (monochrome and foreground) and added new vector drawables for hourglass states.
*   **Documentation**: Streamlined the `README.md` features list and updated the license year to 2026.
