docs: ws-byte-adapter POC complete (GO) — resolve OQ-01, update framing facts
POC at /workspace/ws-byte-adapter-poc/ (not on main), all tests green:
- call round-trip over axum WS ↔ adapter ↔ ChannelsAdapter ↔ channel-0
Dispatcher (published alkcall API only, no forks)
- 3 MiB payload splits across 1 MiB WS messages, byte-intact reassembly
- 20 interleaved calls reassemble without corruption/cross-correlation
Findings merged:
- OQ-01 resolved: byte-stream both directions, bounded mpsc (64 slots)
inbound, outbound chunk-header parsing (frame-as-two-chunks
live-confirmed), 1 MiB message cap with split, flush no-op, close →
EOF → REQ-CH-02
- websocket.md: chunk ≠ frame on channel 0 (frame reassembly required);
operationId is the request payload key
- task ws-byte-adapter → completed with full Summary; ws-upgrade-session
