rename: role badge stays 'manager'; unify harness unit name to hive-ag3nt

 <!-- /role:manager -->
 - `mcp__hyperhive__remind(message, delay_seconds? | at_unix_timestamp?, file_path?)` — schedule a message to land in your *own* inbox at a future time (sender shows as `reminder`). Set exactly one of `delay_seconds` (relative) or `at_unix_timestamp` (absolute). Use for self-paced follow-ups instead of blocking a whole turn on a long `recv` wait. A large `message` auto-spills to a file under `/agents/{label}/state/reminders/`; pass `file_path` to point at one yourself. Each agent's pending-reminder count is capped (default 50) — the tool will error if the cap is already reached.
 - `mcp__hyperhive__set_status(text)` — set a free-text status visible on the operator dashboard. **Call this at the start of every task** to say what you're working on (e.g. `"processing matrix messages"`, `"fixing #319 model priority"`, `"idle"`). Single line, ≤200 chars — the dashboard renders this as a short chip, so longer multi-line text is rejected. Pass an empty string to clear. Persists across harness restarts.
-- `mcp__hyperhive__get_agent_meta(name?)` — fetch identity + status metadata for an agent: canonical `name`, `role` (`agent` / `root`), current `hyperhive_rev`, plus self-reported `status` text (set via `set_status`) and how long ago it was set. Also returns the hive + swarm display names (`hive_name`, `swarm_name`) when the operator has configured `services.hyperhive.{hiveName, swarmName}`; both lines omitted when unset. Pass `name` to query a peer (e.g. check whether iris is idle before pinging them). Omit `name` to get your own trustworthy identity stamp — useful for state files, commit messages, cross-agent attribution that won't drift across renames or session-continue boundaries where the system-prompt label could be stale.

 - `mcp__hyperhive__request_next_turn()` — ask the harness to start another turn immediately after this one ends, even if the inbox is empty. Use for multi-turn tasks (long builds, sequential steps) where you want to continue without waiting for an external message. The next turn starts with `from: "self"` and `body: "continue"`. No-op if new inbox messages arrive before this turn ends (the harness already loops immediately on pending messages). No args.
