Build: use Yarn 4 via Corepack; immutable install with inline builds.
Runtime: enable Corepack as user 'node', use project-local cache (/app/.yarn/cache), add curl; fix ownership.
Entrypoint: generate keys in correct dir; run 'yarn install --immutable --inline-builds' before migrations; wait for Postgres.
Config: enable matomo/css/desktop; notify 'docker compose build' on entrypoint changes.
Docs: rename README title to 'Chess'.

- Move entrypoint to files/ and deploy via copy
- Parameterize APP_KEY_FILE, data dir, and entrypoint paths
- Require explicit PORT/PG envs (remove fallbacks)
- Drop stray header from config/main.yml
- Dockerfile: use templated data dir & entrypoint; keep node user
- Compose: set custom image, adjust volume mapping
- env: derive APP_SCHEME from WEB_PROTOCOL; NODE_ENV from ENVIRONMENT
- tasks: add 01_core and simplify main to include it
