* fix: thread safety for concurrent subagent delegation Four thread-safety fixes that prevent crashes and data races when running multiple subagents concurrently via delegate_task: 1. Remove redirect_stdout/stderr from delegate_tool — mutating global sys.stdout races with the spinner thread when multiple children start concurrently, causing segfaults. Children already run with quiet_mode=True so the redirect was redundant. 2. Split _run_single_child into _build_child_agent (main thread) + _run_single_child (worker thread). AIAgent construction creates httpx/SSL clients which are not thread-safe to initialize concurrently. 3. Add threading.Lock to SessionDB — subagents share the parent's SessionDB and call create_session/append_message from worker threads with no synchronization. 4. Add _active_children_lock to AIAgent — interrupt() iterates _active_children while worker threads append/remove children. 5. Add _client_cache_lock to auxiliary_client — multiple subagent threads may resolve clients concurrently via call_llm(). Based on PR #1471 by peteromallet. * feat: Honcho base_url override via config.yaml + quick command alias type Two features salvaged from PR #1576: 1. Honcho base_url override: allows pointing Hermes at a remote self-hosted Honcho deployment via config.yaml: honcho: base_url: "http://192.168.x.x:8000" When set, this overrides the Honcho SDK's environment mapping (production/local), enabling LAN/VPN Honcho deployments without requiring the server to live on localhost. Uses config.yaml instead of env var (HONCHO_URL) per project convention. 2. Quick command alias type: adds a new 'alias' quick command type that rewrites to another slash command before normal dispatch: quick_commands: sc: type: alias target: /context Supports both CLI and gateway. Arguments are forwarded to the target command.
