atlas 62a2122800 subagent: drop the turn count from a NeedHelp status 
A NeedHelp status is waiting for an answer; `Turn 2 of 5` was
competing with the thing the reader actually needs, which is what it
asked for. Cut it at the describe_stopped call site (it already
formats a distinct sentence per stop reason) rather than in
describe_turns/describe_status, so TurnCap — where the count is the
whole point — and the running-turn case are untouched.

hive-subagent-mcp

Per-agent daemon (hive-subagent-daemon) that spawns nested headless claude sessions on request and serves the tool surface (start/continue/status/interrupt, plus a separate subagent-facing goal_reached/need_help route, one per-session URL) directly over streamable-http. No stdio bridge, no per-turn respawn — an agent's claude reconnects to the same stable URL every turn.

Independent of hive-bash-mcp — a subagent spawns a full nested claude session, a much heavier capability than a bash command, worth its own deployable/restartable unit.

Shape

One bin (hive-subagent-daemon, src/main.rs) built from the crate's own lib (src/lib.rs):

  • session.rs — the actual claude-facing logic: Claude::spawn + RunningClaude::wait/cancel_handle (not InfiniteSession::run, which has no cancel handle to reach in — see the module doc for the v1 scope this trades away), the turn-continuation loop a goal switches on, and the in-memory maps that are the only state this daemon keeps (no task files — a restart stops whatever's running; the actual claude session is the durable store, found again by name via hive_claude::SessionStore).
  • mcp.rs — the rmcp tool routers (the parent's start/continue/status/interrupt on /mcp, the subagent's goal_reached/need_help on /signal/mcp/<token>) + serve_http. Neither signal tool takes a session name: the token in the path is minted per run and resolved to a session before dispatch, so a subagent has no way to name — and therefore no way to signal — a sibling. One route with a path parameter, because the Router is built once at startup and sessions come and go for the daemon's whole life.
  • paths.rs — the in-agent todo-socket path.
