zhi 959e635bb5 fix: 800ms delay before first inbound notification ...

Race observed on first turn: ClaudePlugin emits
notifications/claude/channel before Claude Code finishes registering
the channel handler internally. Claude logs
"MCP server synthesis: Channel notifications registered" ~25ms AFTER
hello_ack arrives. Notifications that arrive earlier are silently
dropped — observed empty session, no turn, curl hangs until timeout.

Fix: on first `inbound` frame after WS hello, wait 800ms before
emitting the MCP notification. Subsequent inbounds skip the wait.

End-to-end verified twice on laptop. Cold-start ~10s, hot path 2-3s.
