Summary

• _path_is_test now matches jest/vitest test file names with any of the usual extensions (.test.tsx, .spec.jsx, .test.mjs, .spec.cts, ...), using vitest's default include pattern. Before, only .test/.spec with .ts and .js counted, so a colocated src/Button.test.tsx went into the source patch and the PR was skipped as no_test_patch.

Test plan

• New test_path_is_test_matches_jsx_tsx_and_module_js_test_files in tests/test_pipeline_pr_runtime.py (four positive cases, plus Button.tsx and test.config.ts staying non-tests). Fails on main, passes here.
• split_patch_and_test_patch on a diff touching src/Button.tsx + src/Button.test.tsx: the test file now lands in the test patch.
• test_pipeline_pr_runtime + test_pipeline_commit_runtime: 91 passed. uv run ruff check . and uv run ruff format --check . clean, generate_metrics.py --check passes.
• Full pytest -q on Windows (without test_modal_transfer.py, which needs harbor from the extras): 213 failed / 68 errors, the same as clean main on this machine (file modes, symlinks); the only difference is the new passing test. generate_prompt_reference.py --check also fails on clean main here because of CRLF checkout, so I couldn't use it locally; this change doesn't touch prompts.

Out of scope

• The test_* prefix rule still only covers .py, .js and .ts; I left it alone.

Closes #190

Keeping this as a draft until #189 is reviewed, so there's only one PR of mine in your queue at a time. It's complete and tested; I'll mark it ready after that one lands.
