fix(docker): auto-detect non-interactive environments (Docker, CI, no-TTY)

- Add comprehensive detection for Docker containers (/.dockerenv, /run/.containerenv)
- Add TTY detection via sys.stdin.isatty() for piped input
- Add OMNIPKG_NONINTERACTIVE env var for explicit override
- Keep existing CI env var detection
- Non-interactive mode now uses all defaults, no input() prompts
- Fixes EOFError crashes in Docker/CI environments
- Resolves #(issue) if applicable
