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.

Agents now connect to the hub with no manual env/flag, and announce
themselves on join — restoring the agreed onboarding flow.
Auto-connect (resolveContext):
- An initialized project WITHOUT a configured serverUrl now falls
through to LAN auto-discovery (previously it went straight to local
mode, so agents in an initialized repo never found the server). The
discovered URL is persisted to the project config, so the next
command is instant.
- IP-change self-heal: when a configured server is unreachable,
runRemote re-discovers the live server and updates the config so the
next command reconnects automatically.
Presence (join-announce):
- POST /announce broadcasts an ephemeral 'agent/joined' event (not
written to disk). New `agenthub hello --agent <name> --role <role>`
posts it; watchers print "AgentHub: <agent> joined (<role>)".
- AgentHubEvent extended with type 'agent' + actions 'joined'/'left';
formatEvent renders presence lines; remoteClient.announce() added.
Tests: formatEvent agent lines + /announce SSE e2e. 109/109 green.
Bump 0.1.2 -> 0.2.0 (CLI --version too).

Closes the documented /events limitation: mutations made through the
local CLI (direct file + SQLite writes, no --server) bypassed the
in-process event bus and were invisible to SSE subscribers. A watcher
(e.g. a Windows client) was therefore NOT triggered when another agent
created a task via plain `agenthub task create`.
- src/server/fsWatch.ts: watch the entity dirs (tasks/handoffs/
decisions/memory); on any .md change, parse the entity and emit the
matching AgentHubEvent. Debounced per-file; self-creates dirs so it
attaches even before the first write.
- src/server/events.ts: shared dedup cache (signature = type🆔stamp)
+ emitChange() so the REST path and the watcher deliver each change
exactly once (no echo when REST writes the file the watcher sees).
- src/server/routes.ts: route emits go through emitChange(); update the
stale limitation comment.
- src/server/index.ts: start/stop the watcher with the server lifecycle.
- tests/sse.test.ts: CLI-write -> SSE, CLI-update -> SSE, and REST
dedup (exactly-once). 102/102 green.
Effect: a watcher is auto-triggered the instant any agent creates a
task, with or without --server. Bump 0.1.0 -> 0.1.1.

- src/server/events.ts: in-process EventEmitter bus (AgentHubEventBus);
singleton per server process, unlimited listeners for SSE fan-out.
- src/server/routes.ts: GET /events SSE endpoint — keepalive every 25 s,
optional ?role= server-side filter, reply.hijack() for clean streaming;
eventBus.publish() called on every successful mutating route (POST tasks/
handoffs/decisions/memory, PATCH tasks/:id).
- src/cli/commands/watch.ts: SSE client using Node fetch + ReadableStream
reader; exports parseSSEBuffer + formatEvent for testability; --once flag
exits 0 after first event (turn-based agent use case); --role for client-
side filtering (additive to server-side filter).
- src/cli/index.ts: register agenthub watch command via resolveContext.
- tests/sse.test.ts: 18 new tests (74 total, all green) — unit tests for
parseSSEBuffer + formatEvent, integration tests for eventBus on each
mutation type, E2E SSE stream + role-filter tests over real HTTP.
Limitation (documented): only REST mutations through the server emit events.
Local-CLI writes (direct file+SQLite) are invisible to subscribers — a
filesystem-watch increment is deferred to a later phase.
