Implement comprehensive code coverage functionality with hierarchical navigation and LCOV-compatible visualization. Frontend: - Add CoverageStatistics component for hierarchical directory/file navigation with coverage metrics (line and function coverage) - Enhance CodeCoverageView with LCOV-style line-by-line coverage display: * Two-column layout (line data + source code) * Right-aligned execution counts * Color-coded coverage (green/yellow/red based on thresholds) * Breadcrumb navigation with one-level-at-a-time navigation * Coverage summary table matching LCOV format - Add routes for coverage statistics and file views - Update component exports Backend: - Enhance mass_store_run.py with 6-strategy path matching for coverage data association (exact, trimmed, filename-only, both in-memory and DB queries) - Add duplicate coverage line detection to prevent data duplication - Protect files with coverage data from cleanup in db_cleanup.py - Add Tasks endpoint to webpack dev server proxy configuration Configuration: - Update .gitignore to exclude runtime-generated analysis and coverage files (plist, gcda, gcno, coverage.json, reports/, etc.) The implementation follows LCOV's coverage calculation logic: - Only executable lines are counted (excludes comments, includes, closing braces) - Simple return statements are excluded from coverage metrics - Coverage percentages match LCOV calculations exactly - Display format matches LCOV HTML reports
