Release readiness report

The release readiness report creates a small Markdown and JSON summary for the release record.

scripts/release-readiness-report.sh --output-dir dist/release-readiness

Use --run-checks to run selected local checks and capture their logs:

scripts/release-readiness-report.sh --output-dir dist/release-readiness --run-checks

The output directory contains release-readiness.md, release-readiness.json and optional command logs.
