recv: None = peek, positive value = opt-in long-poll

old behavior: omitted wait_seconds fell through to the 30s
RECV_LONG_POLL_DEFAULT — claude calling 'is there anything in
my inbox right now?' between actions blocked the turn for half
a minute. flip the semantics: None (or 0) returns immediately,
positive value parks up to MAX (180s, unchanged). cleaner
'peek vs wait' distinction; tool descriptions + agent/manager
prompts updated to point at the new shape.

harness's own serve loops in hive-ag3nt + hive-m1nd relied on
the old default for their inbox poll. they now explicitly pass
wait_seconds: Some(180) to opt into the full park — same
effective behavior as before, just spelled out.

+### Waking the agent from inside the container
+
+External MCP servers (and any other in-container process) can
+inject a wake-up event into the agent's inbox via the per-agent
+socket at `/run/hive/mcp.sock`. Two equivalent paths:
+
+- **Shell out to `hive-ag3nt wake --from <label> --body <text>`**
+  (use `--body -` to read body from stdin). Already on the
+  container's `PATH` since the harness binary is in
+  `systemPackages`. Convenient for shell-script integrations.
+
+- **Speak the wire protocol directly** — JSON-line over the
+  unix socket: `{"cmd":"wake","from":"matrix","body":"new dm
+  from @alice"}\n`. Same shape any other AgentRequest uses;
+  see `hive-sh4re::AgentRequest::Wake`.
+
+The wake event lands in the broker as `{from:<label>,
+to:<agent>, body}`, which wakes whatever `recv` call the
+harness is currently blocked on. Next turn fires with the
+wake prompt formed from that message — claude sees "from:
+matrix" (or whatever label) and reacts.
+
+Identity = socket: anything that can connect to
+`/run/hive/mcp.sock` is implicitly trusted to inject these,
+which is fine because the bind-mount is the agent's own
+container only.
