Function read_project_paths 

pub fn read_project_paths(project_root: &Path) -> ProjectPaths

v0.113: read bynk.toml from project_root. Returns the conventional layout (see ProjectPaths::conventional) if the file is missing or declares no [paths] include. Honours include / exclude under [paths], each an array of path strings; anything else is ignored. A minimal hand-rolled TOML reader — we only need string and string-array values here.
