Pure parser for npm root -g stdout. Returns the trimmed path or None on empty input. Extracted so the helper logic is unit- testable without shelling out.

parse_package_name

Parse a full npm package name into optional namespace and bare name.

parse_pnpm_root_output

Pure parser for pnpm root -g stdout. Returns the trimmed path or None on empty input.

parse_yarn_dir_output
