Extends the WebTransport interface and its three implementations
(QUIC-backed, in-memory fake, peer-stripped demux) with typed
error-code cancel paths so moq-lite Lite-03's M2/M3 audit items can
land.
QUIC layer (`:quic`):
- `StrippedWtStream` gains optional `reset` and `stopSending`
closures, wired by `WtPeerStreamDemux.emitStripped` through
`QuicStream.resetStream(errorCode)` /
`QuicStream.stopSending(errorCode)` + `driver.wakeup()` so the
frames actually leave the connection. `reset` is null on
peer-initiated uni streams (no send half on our side);
`stopSending` is unconditional (every surfaced stream has a
read side).
WebTransport interface (`:nestsClient`):
- `WebTransportReadStream.stopSending(errorCode: Long)` —
suspending; first-call-wins.
- `WebTransportWriteStream.reset(errorCode: Long)` —
suspending; first-call-wins. Distinct from the existing
graceful `finish()` / FIN.
Adapters:
- `QuicBidiStreamAdapter`, `QuicReadStreamAdapter`,
`QuicUniWriteStreamAdapter` route directly to the underlying
`QuicStream` API.
- `StrippedWtReadStreamAdapter` /
`StrippedWtBidiStreamAdapter` route through the demux's
closures; defensive `?:` fallbacks defend against a future
demux bug that forgets to wire a closure.
- `FakeBidiStream`, `FakeReadStream`, `ChannelWriteStream` (the
in-memory test transport) record reset / stopSending codes
in shared `AtomicLong` cells so tests can assert "the peer
reset with code X" / "the listener stopSending with code Y"
via new `lastResetCode` / `lastStopSendingCode` /
`lastPeerResetCode` / `lastPeerStopSendingCode` properties.
Sentinel `NO_CODE = Long.MIN_VALUE` distinguishes "not called"
from a legitimate code 0.
Pure plumbing — no moq-lite call sites use the new methods yet.
Subsequent commits wire M3 (publisher Drop reply uses
reset(errorCode)) and M2 (listener group-cancel uses
stopSending(errorCode)).
