-- Path B for loops (P2): give every enabled loop its own per-loop team
-- container so scheduled runs don't share state / memory with other loops
-- or with the research pipeline. Two nullable columns:
--
--   zeroclaw_container   — deterministic docker container name; NULL
--                          until the first `run_now` / `webhook_receive`
--                          / scheduler tick spawns one, set + reused
--                          on subsequent fires.
--   zeroclaw_gateway_url — http://<container>:42617; topology_worker
--                          prefers this over the workspace-wide URL when
--                          the run belongs to a loop with a spawned
--                          container.
--
-- Fallback semantics match research: NULL means "no per-loop container
-- yet, use the env-derived executor". Never-spawned loops (e.g. from
-- workspaces where docker isn't reachable) keep firing on the shared
-- gateway — degraded, not broken.
