feat(gradle): multi-task batch filter

[Nava2]

Summary

• Split multi-task Gradle output into per-task sections using > Task :...: boundary markers
• Apply task-specific filters to each section (compile, test, detekt)
• Failed sections shown with full filtered details; successful tasks collapsed to taskName ✓
• Trailing content (FAILURE:, BUILD FAILED, actionable tasks) preserved
• detect_task_type_from_name() reuses TASK_TYPE_REGISTRY matchers
• Integration test detection per-section via is_integration_task_name()
• Hook integration: ./gradlew and gradle discover rules + CLAUDE.md/CHANGELOG.md updates
