feat: diff-based test selection for E2E and LLM-judge evals (v0.6.1.0) (#139) * feat: diff-based test selection for E2E and LLM-judge evals Each test declares file dependencies in a TOUCHFILES map. The test runner checks git diff against the base branch and only runs tests whose dependencies were modified. Global touchfiles (session-runner, eval-store, gen-skill-docs) trigger all tests. New scripts: test:e2e:all, test:evals:all, eval:select Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * chore: bump version and changelog (v0.6.1.0) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: plan-design-review-audit eval — bump turns to 30, add efficiency hints The test was flaky at 20 turns because the agent reads a 300-line SKILL.md, navigates, extracts design data, and writes a report. Added hints to skip preamble/batch commands/write early while still testing the real SKILL.md. Now completes in ~13 turns consistently.
