glm-5.2 528cfa0367 docs(adr): 092 — remove Connection::from_stream, from_bidi is the only public constructor
The earlier draft kept from_stream as an 'escape hatch' for already-split
transports. That bakes the split into the constructor API — the same
split-leaf shape pushed one step earlier. The cleaner normalization: the
split never crosses a crate boundary as part of a constructor.

- Connection::from_bidi is the only public stream constructor.
- Connection::from_stream(send, recv, ...) is removed.
- The channels reassembly path joins MpscSendStream/MpscRecvStream itself
  via tokio::io::join (one line) and calls from_bidi.
- The call crate's 5 test stub sites do tokio::io::split(x) then
  from_stream — they become from_bidi(x) directly. The split was always
  gratuitous at the call site.
- SendStream::from_stream / RecvStream::from_stream (per-half boxing for
  into_sub_streams() and the SubStreamHandle leaves) are retained — not
  constructors that feed Connection.
