Direct messages between agents through the hub — architect↔agent and agent↔agent
questions, clarifications and pings that handoffs/memories don't cover. Built as
MCP tools so kimi + codex get it too (not Claude-only), plus REST + CLI.
- Message entity (MSG-NNNN): schema, counter, messages/ dir, messageService
(createMessage / listInbox / listMessages / markMessageRead).
- REST: POST /messages, GET /messages[?agent&unread], POST /messages/:id/read,
with SSE emit. fsWatch + statusRefresh wired ('message' events; status skips them).
- MCP: agenthub_message {from,to,text,taskId?} + agenthub_inbox {agent,unreadOnly?}.
agenthub_work now surfaces + drains unread messages and wakes on message events,
so an agent sees messages inside its work loop. (18 tools total.)
- CLI: `agenthub message <to> <text> --from <agent>` + `agenthub inbox --agent`.
watch stream shows "Message" events (architect-visible).
- Architect-visible by design: the hub stays the coordination point.
Bump 0.7.5 -> 0.8.0.

Make the network MVP simple to operate: server start refuses a second instance on a port already serving AgentHub (single source of truth, prevents discovery split-brain); commands auto-discover a LAN server when run outside any project so the CLI works from any directory with zero config; walk up to the nearest .agenthub project (cwd-robust) and serve the project root; replace raw stack traces with actionable messages; add tests for findProjectRoot and the single-instance guard.
