feat: poker-session notes are session narration, tagged by construction

The HUD's "her notes" panel showed any journal/note entry in the session's time
window — which swept in her *autonomous* journaling (dream-cycle reflections,
thought loop, existential musings) that merely overlapped in time. So a poker
session displayed her feelings, not the night.

Fix both halves:
- Identity: the `note` tool stamps `source=poker:{id}` when a session is live, so
  a session note is identifiable by construction. The HUD filters on that tag
  (kind='note' only) instead of a time window — her journaling has a different
  source and can never leak onto the poker HUD. `journal_write` stays her private
  journal and never shows here.
- Behavior: the Cash card now tells her to use `note` as a running SESSION LOG —
  factual beats a hand/stack log misses (table dynamics, Brian's arc, momentum),
  beat-reporter not diarist — and explicitly keeps feelings/reflection off the
  table. The note tool spec echoes this for the live-session case.
