fix: lexical symlink containment, assert project_root consistency

- uninstall() now uses os.path.normpath for lexical containment check
  instead of resolve(), so in-project symlinks pointing outside are
  still properly removed
- setup() asserts manifest.project_root matches the passed project_root
  to prevent path mismatches between file operations and manifest
  recording
