Function cursor_project_slug

src/sessions/cursor.rs:550–560

Compute the `~/.cursor/projects` directory slug Cursor derives from a workspace path: every normal path component joined with `-`, case preserved (verified against real `~/.cursor/projects` entries). Returns `None` for non-UTF-8, relative, or traversal-containing paths.
