Fix HTTP/2 RST_STREAM behaviour, add auto-drain, deprecate 'aborted', fix related compat API issues - #63249

… with Code.Unavailable

When a peer (typically a proxy such as Envoy) resets a stream with
RST_STREAM code NO_ERROR before the response completed, Node's http2
client (pre nodejs/node#63249) surfaces the truncation as a clean,
error-free end-of-stream. The protocol layer then fails parsing the
truncated body with misleading errors: "protocol error: incomplete
envelope" (invalid_argument) or "protocol error: missing status"
(internal).

Track whether a request that declared "TE: trailers" (as gRPC requests
always do) received its terminating trailers or a trailers-only
response, and reject with Code.Unavailable from the close handler when
the stream ended with rstCode 0 without either.

Verified: package tests 113/113 (5 new failure-mode tests fail without
the fix, 4 new non-regression tests), conformance 6258/6258 client and
4718/4718 server.

## Human summary

Improves the detection of completed requests by additionally checking
for `res.writableEnded`. This works around a quirk in Node.js when
running in http/2, which is resolved in 26+:
nodejs/node#63249.

Checking for `res.writableEnded` does not change anything when running
in http/1, as this is always true when `res.writableFinished`. This
changes behavior for http/2 by properly detecting aborted requests.

This should result in downstream consumers having a more reliable signal
for when a client request is aborted, allowing them to cancel jobs such
as in-flight ES requests regardless of http protocol.

We detected this while writing scout tests for
#285153

## AI description
When an HTTP/2 client destroys a stream mid-request (RST_STREAM /
NGHTTP2_CANCEL, e.g. an AbortController cancel or browser navigation),
Node's Http2ServerResponse emits 'close' with writableFinished === true
even though nothing was written. isCompleted() relied on
writableFinished alone, so the !isCompleted filter swallowed the event
and request.events.aborted$ never fired — consumers (route handlers,
auth providers) could not observe HTTP/2 client aborts. HTTP/1 was
unaffected because writableFinished stays false there.

Treat a request as completed only when writableFinished &&
writableEnded: writableEnded only becomes true once the server actually
ended the response, and is truthful on both protocols and for abrupt
TCP-level disconnects.

Adds integration coverage in http2_protocol.test.ts driving a real
HTTP/2 TLS session that resets the stream while the handler is pending,
plus a control test asserting completed$ (and not aborted$) on normal
completion.
