Phase 14: dreaming as an opt-in, budgeted, non-acting idle mode

- dreaming.Service: deterministic memory replay sample keyed by dream id,
  vocabulary-based association of unlinked memory pairs (similar_to edges +
  dream_association events), speculative hypotheses as hypothesis-kind beliefs
  with two weak memory citations (starts ~0.30, asserted <= 0.35)
- Run marks the context forbidden for capabilities before anything else;
  test proves Invoke refuses inside a dream
- per-mind settings: enabled (default off), hours window (wraps midnight),
  interval, model-call / memory / hypothesis caps; global pause switch
- optional model wording via new `dream` prompt (role hypothesise)
- promotion adds operator evidence, rejection retracts the belief; both
  audited and recorded as operator actions
