fix: improve macOS deployment compatibility and Docker build hygiene

- .gitignore: add missing macOS artifacts (.AppleDouble, .Spotlight-V100, etc.)
- Makefile: fix `make ip` to detect network interfaces on both macOS and Linux
  (adds `ip` command fallback, guards macOS-only `ipconfig` behind uname check)
- Makefile: add `make install-creative` target with Apple Silicon Metal guidance
- Dockerfile: install deps from pyproject.toml instead of duplicating the list,
  eliminating drift between Dockerfile and pyproject.toml
- docker-compose.yml: document data/ directory prerequisite for bind-mount volume
