Adds a synchronous sub-agent spawning tool that lets the orchestrator
delegate tasks to a specific role's model and tool set.
- cortex/tools/agents.py: spawn_agent(task, role, tier, timeout, max_rounds)
- Supports local_openai and gemini_api model types
- Per-host asyncio semaphore (keyed by host_id or model type)
- asyncio.wait_for() enforces timeout; admin-only tool
- cortex/model_registry.py: max_concurrent field in host schema (default 3,
clamped 1-20); backfilled on _normalize() for existing hosts
- cortex/routers/local_llm.py + local_llm.html: "Max parallel" number input
in host add/edit forms
- cortex/tools/__init__.py: spawn_agent registered in TOOL_CATEGORIES["Agents"],
_CALLABLES, TOOL_ROLES (admin), and _ALL_DECLARATIONS
- Docs: TOOLS.md count 44→45, spawn_agent section; HELP.md tool table updated;
ARCH__FUTURE.md Round 2 completed items; TODO__Agents.md spawn_agent checked;
CLAUDE.md tool count and list updated
