Tautest v1.3.0

Highlights

• Added tautest demo for a quick local passing-tests-but-surviving-mutant walkthrough.
• Added GitHub Action cache restore/save visibility to the job summary.
• Fixed the GitHub Action CLI fallback so npm/yarn/bun projects do not fall back to pnpm exec by mistake.
• Updated release metadata and package discovery keywords for changed-line mutation testing.
• Patched the production dependency audit by overriding transitive qs to 6.15.2.

Verification
