Build and Test

• Migrated to Gradle (Java 21).
• To build locally: ./gradlew clean build
• To test: ./gradlew test (unit + naming snapshots)
• Integration tests skip if secrets missing.

Secrets

• GDRIVE_SERVICE_ACCOUNT_JSON: Masked JSON for Drive access.
• GDRIVE_PARENT_ID_RAW: Folder ID for raw clips.
• GDRIVE_PARENT_ID_EDITS: Folder ID for edited clips.

CI Updates

• Workflow: .github/workflows/ci.yml now handles build/test, integration smoke (skips without secrets), and releases.
• Explained: Updates ensure green CI without secrets; preserved naming/filename logic.

Flags

• AUTOMATION_DRY_RUN=1: Dry run mode.
• AUTOMATION_FAKE_FFMPEG=1: Mock FFmpeg for CI.
