Three small follow-ups from the audit pass:
1. Drop redundant `challengeData.copyOf()` in
`queuePathResponseLocked` — the parser produces a fresh
ByteArray per PATH_CHALLENGE via `QuicReader.readBytes`'s
`copyOfRange`, so the defensive copy was a wasted allocation.
One-line fix.
2. Rename `pendingPathResponses` → `pendingPathChallengePayloads`.
The queue holds inbound CHALLENGE payloads we owe RESPONSES
for — old name conflated the two. Pure rename across
QuicConnection / Parser / Writer / PathValidationTest.
3. Extract shared `newConnectedClient(...)` test fixture
(`ConnectedClientFixture.kt`). The 6 test files each repeated
~40 lines of identical handshake-pipe boilerplate; folded into
one parameterized helper accepting transport-cap overrides.
Net −164 lines across the test tree; per-test helper is now a
one-liner that documents the cap shape.
No behavior change. Full quic suite + amethyst hook test green.
