Wire the shared-palace option (implemented in mempalace-toolkit's mempalace.ts)
into the container:
- .env.example: document MEMPALACE_REMOTE_URL / MEMPALACE_REMOTE_TOKEN (env_file-only,
per this repo's convention).
- docker-compose.mempalace.yml: optional shared server (mempalace-mcp --transport http),
loopback-bound by default.
- docker-compose.yml: local-vs-external note on the palace-volume comment.
- README + CHANGELOG (Unreleased).
