feat(family): family canon reaches the session - entry readout, retrieval reach, skill, report cue (milestone 463 step 6, #4992)

- enter_project carries a `family` key, but only when the project has
  something to answer: counts of unassessed, owed and to-recheck answers,
  each with the list_family_adoptions call that lists it. It shows on every
  entry, never by platform touch: entry is when work is chosen, and an
  unanswered idea is otherwise invisible.
- Retrieval: a widened project search (include_global_kinds) now also
  reaches the canon ideas on the project's platforms. It also reaches their
  references in the project's languages, or all of them when none matches.
  An off-platform project gets none, and the plain project filter (the
  duplicate gate) is unchanged.
- Closing a task returns `family_owed`, the owed answers filed while it was
  open, and the report cue asks for them to be named.
- New plugin skill family-canon (moment work.record) covers when to
  evaluate a promotion, answering in order, what counts as a reason, the
  precedent reflex and the conflict order. _INSTRUCTIONS, create_note,
  create_snippet, classify_shapes and reporting-back point at it.
  The plugin version is minted.
