refactor(hooks): rename interactive-bash-blocker to non-interactive-env

- Replace regex-based command blocking with environment configuration
- Add cross-platform null device support (NUL for Windows, /dev/null for Unix)
- Wrap all bash commands with non-interactive environment variables
- Only block TUI programs that require full PTY
- Update schema, README docs, and all imports/exports
