fix: map devcontainer port 4242 to host 51888#34
Merged
Conversation
Let mind-map use its default port (4242) inside the container. Docker maps it to 51888 on the host, avoiding conflict with the production mind-map service on host port 4242. Set onAutoForward to ignore so VS Code doesn't also forward 4242.
mind-map uses its default port (4242) inside the container. Docker maps it to host 51888. No env var indirection needed. Cleaned up: devcontainer.json, launch.json, tasks.json

Let mind-map use its default port (4242) inside the devcontainer. Docker maps container:4242 → host:51888, so the dev server never conflicts with the production service on host port 4242.
