v0.1.8

What changed

• Updated the GitHub Action Marketplace description to say exactly what ReproGate checks: reproduction steps, environment details, and logs.
• Tightened the README opening so Marketplace readers see the Action value before CLI details.
• Updated README, recipes, and generated workflow examples to JinRudy/reprogate@v0.1.8.

Verification

• go test ./...
• git diff --check
• GitHub Actions reprogate and action-self-test passed on the release commit.
