podman run -d returns before the container process is running.
CS Core's claude-code check immediately calls our wrapper, which
found the container not yet running and exited 1 — causing the
"claude-code not found" error.
Add a poll loop (10 x 0.5s) that waits for State.Running=true
before setting PATH and launching CS Core.
