The previous `docker run -d --entrypoint="" ... sleep 60` bypassed the
entrypoint chain entirely, so entrypoint-user.sh never ran, so
pi-toolkit/install.sh never deployed keybindings + extensions to
~/.pi/agent/. Result: 4/14 smoke checks always failed.
Match opencode-devbox's pattern: `docker run -d --rm "$IMAGE" tail -f
/dev/null` keeps the entrypoint chain intact and overrides only CMD.
((VAR++)) returns the OLD value, so when PASS=0 the first ✅ check
caused exit code 1, killing the script under set -e. Use VAR=$((VAR+1))
which always returns 0. Same pattern as opencode-devbox's smoke-test.
pi coding-agent container built on opencode-devbox:base-latest.
Includes Dockerfile, docker-compose, CI workflow, smoke-test,
README, CHANGELOG, AGENTS.md.
