Three-commit plan to unblock api.alk.dev (standard TCP+TLS HTTP), alknet-ssh
(per-channel dispatch over russh), and alknet-blobs (iroh 1.0 prerequisite):
1. Drop dead irpc/irpc-derive workspace deps (never imported by any .rs file)
2. Migrate alknet-core iroh 0.35 -> 1.0 (3 edits in build_iroh_endpoint + Cargo.toml)
3. Add Connection::from_stream / from_bidi — a generic single-stream connection
kind that makes every ProtocolHandler work over TCP+TLS, SSH channels,
WebTransport streams, and wasm without handler code changes. Rename the
existing stream-level Mock variants to Stream (they were already generic
stream holders, just misnamed).
The yield-once accept_bi contract: QUIC yields many streams, everything else
yields one. Handlers that loop (tty) get one iteration; handlers that call
once (http) get the stream directly. Both correct, no branching on transport.
No ProtocolHandler trait shape change (one-way door per ADR-009). SSH's
per-channel dispatch is handler-internal, same pattern as TtyAdapter's
per-stream dispatch. Incorporates ../iroh-update/findings.md by reference.
