fix: divi-node-get rev + short type, divi-outline id validation

- lit/divi-node-get now also returns the post-level rev (Rev::ofPost, same
  optimistic lock lit-content-update needs) next to tree_rev, and reports a
  node's type as the short name ("button"), matching lit-divi-outline instead
  of the namespaced "divi/button". description() notes that $variable(...)$
  values shown are re-validated when written, never taken over unchecked.
- lit/divi-outline validates its optional `id` input against the same
  path-ID pattern lit-divi-node-get uses (a malformed id is now a validation
  error, not a "not found"), and its outputSchema's per-node `required` list
  now includes info/presets/children, which are always present.
- NodeSummary::label() (the admin label shown in outlines and node-get)
  whitespace-normalizes and bounds its result via Text::shorten(), like every
  other summary string, instead of returning a raw, unbounded value.
- docs/superpowers/notes/.../etappe-2a-abnahme.md corrected: only a global
  module is "nur lesbar" - a specialty section is a normal, editable
  divi/section block; the outline just marks it "[specialty]".
