Report teardown and TEST_DIR cleanup failures separately.

If caseTeardown rejects and removeTreeWithRetry(TEST_DIR) also throws, the finally block throws teardownFailure and masks the removal error. Capture the cleanup error and report both errors after the cleanup block. The inspected repository does not configure or enforce Biome's noUnsafeFinally rule, so remove that unsupported claim.

minimal, and validate.

In `@tests/server/server-live.test.ts` at line 88, In the test cleanup flow,
preserve both failures when `caseTeardown` and `removeTreeWithRetry(TEST_DIR)`
fail. Capture errors from teardown and cleanup separately, then report both
together when both occurred and propagate whichever single error occurred
otherwise; keep the remaining cleanup actions running.
