Introduces a `is_benchmark` intent flag to streamline app startup during Baseline Profile generation, bypassing setup screens and permission dialogs for a more stable and direct launch to the main screen.

- **MainActivity.kt**:
  - Reads a new `is_benchmark` boolean extra from the intent.
  - Skips the `SetupScreen` if `is_benchmark` is true.
  - Prevents the "All Files Access" dialog from appearing during benchmark runs.

- **BaselineProfileGenerator.kt**:
  - Simplifies the generation script to perform only a cold start and a brief wait, removing complex UI interactions (tab navigation, scrolling, sheet opening) that caused instability.
  - Launches the app with the `--ez is_benchmark true` flag to ensure a direct path to the `HomeScreen`.
  - Grants `MANAGE_EXTERNAL_STORAGE` and `POST_NOTIFICATIONS` permissions via shell commands before the run to avoid system dialogs.

- **HomeScreen.kt**:
  - Adds `ReportDrawnWhen` to signal when the screen is fully drawn, using the presence of songs or the `is_benchmark` flag as a trigger.
  - Suppresses the app rebrand dialog when in benchmark mode.

- **Build & Dependencies**:
  - Adds a new `benchmark` build type in `app/build.gradle.kts` that inherits from `release` but is debuggable.
  - Updates `benchmark-macro-junit4` and `baselineprofile` libraries to version `1.3.3`.
  - Includes the `baselineprofile` module in the Gradle project settings.
