moq-lite Lite-03 conveys application-level errors on any stream via
`RESET_STREAM(application_error_code u32)` (audit M3). Pre-fix, our
publisher's two SubscribeDrop reply paths
(`BROADCAST_DOES_NOT_EXIST`, `TRACK_DOES_NOT_EXIST`) wrote the Drop
body and then `bidi.finish()` — a graceful FIN — which overlapped
with "publisher gracefully shut down." A subscriber watching only
the QUIC layer (no body decode) couldn't tell rejection from
shutdown.
Replace the trailing `bidi.finish()` with `bidi.reset(errorCode)`
in both Drop paths. The errorCode matches the body's `errorCode`
field so a peer that decodes the Drop sees the same number as one
that only sees the RESET_STREAM frame. The plumbing landed in the
prior commit (`feat(quic,nestsclient): plumb RESET_STREAM +
STOP_SENDING through WebTransport`).
Tests: existing `publisher_replies_subscribeDrop_when_*` regressions
gain an additional `lastPeerResetCode` assertion via
`FakeBidiStream`, locking the typed-error contract.
