LCOV Coverage Check

A composite GitHub Action that parses LCOV coverage files and enforces coverage standards on pull requests.

Features

• Coverage summary — Reports overall line coverage from any LCOV file.
• Baseline comparison — Compare current coverage against a baseline LCOV file to catch regressions.
• New file thresholds — Enforce a minimum coverage percentage on newly added files (configurable path prefix and threshold).
• Per-file regression guard — Optionally fail when modified files lose coverage vs. the baseline.
• PR comments — Post a formatted coverage summary directly on the pull request (requires github-token).
• Outputs — Exposes overall-coverage, baseline-coverage, and passed for downstream steps.
