fix(poker): read showdowns off the tool, not by eye — and cut the mush

The HAND fragment let her narrate a finished board from memory: she called
quad kings "kings full" and never noticed Brian FLOPPED quads, then wrapped it
in variance-evens-out / resilience filler. Two fixes to _F_HAND:

- Correctness: at a showdown where both hands are known, call analyze_spot on
  the full board to confirm made hands + winner BEFORE commenting; name his hand
  class by the street it mattered ("flopped quads"). The eval already existed —
  she just never reached for it on a resolved hand. (It also catches impossible
  cards, e.g. a villain card already on the board.)
- Register: ban reflexive praise / variance-evens-out / life-lesson / cross-hand
  pep talk; if there's genuinely no leak, say so instead of inventing a takeaway.
  Surgical here; the full voice pass stays with the persona branch.

Verified live on the exact quad-kings hand (cloud/gpt-4o-mini): she now logs,
calls analyze_spot, reads quads-vs-quads correctly, and calls it a cooler with
no leak. Guard tests added. Full suite 212 green.
