chore(embedded): cut v0.0.27-beta

- browse hovercard shows 'Your permissions' (verbs) + 'Your roles' (cascade
  roles) for the hovered folder/file; server adds path_roles to
  /.profile/access?path=.
- read-only YAML/.zddc viewer is selectable/copyable (readOnly:true, not
  'nocursor') without enabling admin mode.
- /.profile/access?path= returns only the path-scoped payload (skips the
  global project + admin-subtree tree walks).
