Test Improvement

Files / functions claimed: __tests__/utils/config.test.ts (parseProwConfig › label values and unknown-key logging; mergeProwConfig). Tests only; no src/, dist/ or docs change. Disjoint from every open held PR (#510–#533): none touches __tests__/utils/config.test.ts or src/utils/config.ts.

A single-operator mutation probe over src/utils/config.ts on main @ 88241f4 (258 mutants, details on #534) left two non-equivalent mutants alive against the full npx vitest related src/utils/config.ts --run set (70 files / 1498 tests) and three more that only __tests__/utils/labelCatalog.test.ts › "de-duplicates case-insensitively" happened to kill. This adds three tests that kill all six in config.test.ts itself:

line	mutant	test
740	lgtm: { ...base.lgtm, ...over.lgtm } → { ...over.lgtm, ...over.lgtm }	mergeProwConfig › keeps the organization lgtm and sweep sections when the repository names neither, and lets the repository override them
741	sweep: { ...base.sweep, ...over.sweep } → { ...over.sweep, ...over.sweep }	same
451	section.exclusive === undefined → === null	label values › accepts an object value without a color, in a list and in a values mapping without exclusive
469	value.color === undefined → !== undefined	same
472	value.color !== undefined → !== null	same
421	unknown.length > 0 → >= 0	parseProwConfig › does not log when every top level key is known

The first two matter most: an organization-wide lgtm.bind_to_commit or sweep.lookback would have been silently dropped for every repository that ships its own prow.yaml, and nothing in the suite would have noticed.

Verification (this branch, local)

• npx vitest run __tests__/utils/config.test.ts: 103 passed (100 before)
• each of the six mutants applied in turn to src/utils/config.ts, npx vitest run __tests__/utils/config.test.ts: all six fail the run
• npx eslint __tests__/utils/config.test.ts: clean

Important

Held for human review by the hive's ACMM level gate.

This PR was opened by the "quality" agent while Hive policy required a human checkpoint for that agent. Agent PRs are held at ACMM L3–L5; an outreach PR that targets a repository this hive does not manage is held at every level because it publishes project-facing communication into someone else's project.

Hive will keep the hold label until a human removes it. Operators can make a deliberate one-off release during an ACMM level change with release_level_holds=true, but level changes never release this hold automatically.

Copilot review performed under the maintainer's explicit authorization to update, review, release reviewed holds, and merge eligible PRs in this cleanup.

Organization lgtm/sweep inheritance and repository overrides are both asserted. Optional label color/exclusive fields parse as intended. This is a regression-test change, not a production config fix.

Verified successful build-test, e2e-coverage and DCO results on head 15b904f. Any folded issue findings remain assigned to the canonical destinations in the updated scope tables.
