The raw socket handoff no longer needs Socket#setTimeout; an ordinary connection deadline keeps the timeout behavior while avoiding an internal socket timeout listener that has no reliable UDS integration path to exercise.
Constraint: Keep Codecov coverage honest without adding ignore pragmas, mocks, or fallback suppression.
Rejected: c8 ignore on the timeout listener | hides the uncovered branch instead of simplifying the lifecycle.
Rejected: keep Socket#setTimeout listener | leaves a socket listener lifecycle to manage for a connect-only deadline.
Confidence: high
Scope-risk: narrow
Directive: Keep connectToPeer errors caller-owned via onSocketError and reject pre-connect failures with UdsPeerConnectionError.
