Delegating right after spawn failed: herdr reports 'idle' during the worker's
boot, so the injector delivered into a not-ready TUI (paste lost) and wedged the
worker. Two fixes:
- Readiness gate: a worker is 'available' only once its Claude connects the bridge
MCP (the daemon observes it via peer-PID->terminal). WorkerPresence tracks it; the
injector holds the first delivery until present, so it never pastes into the boot
window. Exposed as 'ready' on GET /sessions/{id}/status.
- Submission nudge: the Enter accompanying a delivery can race the paste (esp. right
as the TUI becomes ready), leaving text unsubmitted. While a delivered message
stays idle (not picked up), the injector re-sends Enter each poll until the worker
starts (WORKING) or the grace expires.
Validated live: spawn + immediate delegate now holds during boot (ready=false),
delivers on MCP-connect, re-nudges Enter, worker replies. 102 tests green.
