feat: auto-accumulating villain dossiers + player lookup (poker B)

Named players in recorded hands now auto-enrich a persistent dossier, and stats
emerge once the sample is big enough — laying groundwork for A.

- poker: player_observations table (per named player per hand: vpip/pfr/saw_flop/
  showed/cards/summary); record_hand auto-links named players via link_hand_players;
  player_profile(name) returns dossier + reads + shown hands, with inferred
  VPIP/PFR/WTSD gated behind MIN_STATS_SAMPLE (12) so thin samples don't lie;
  list_players()
- player_profile tool ("what do I know about X"); thin files return a blunt
  "don't generalize" directive
- persona: she MUST call player_profile before discussing an opponent and answer
  only from it — fixes observed confabulation (she invented a whole read from one
  hand / from memory). Verified: now reports only the real logged hand.
- tests: observation linking, profile, stat-emergence at sample threshold
