atlas 44984e0d36 move install_crypto_provider to swarm-secret-client 
The rustls provider install is process setup every swarm binary runs, and
swarm-secret-client depends on no other swarm crate, so a binary that only
needs the provider and the store no longer links the queue client.

- swarm-secret-client/src/lib.rs, Cargo.toml: the function, its test, a
  `//!` line on why it lives there, and the rustls dependency; rustls
  `ring` as a dev-dependency feature, so the test builds both providers as
  the binaries do and fails if the install is dropped.
- swarm-queue-client/src/lib.rs, Cargo.toml: function and test removed;
  `connect()` calls the secret client's; rustls dropped (no other use),
  swarm-secret-client added.
- swarm-metrics-auth/Cargo.toml: drop swarm-queue-client, whose only use
  was the provider; the binary no longer links async-nats.
- swarm-logs-auth, swarm-logs, swarm-metrics, swarm-ci-metrics Cargo.toml:
  the dep comment no longer names the provider (they keep the dep for
  agent_token / the OIDC mint).
- Cargo.toml: the rustls comment names the provider's new home.
- 14 call sites (hive-agent, hive-c0re, hive-subagent-mcp x2,
  swarm-builder, swarm-ci-metrics, swarm-claude-login, swarm-controller,
  swarm-logs-auth, swarm-logs, swarm-metrics-auth, swarm-metrics,
  swarm-nats-auth, swarm-review-classifier): one-line path change.
- Cargo.lock: the dependency edges above.

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.
