feat(prompting): harden the poker classifier against real-world phrasings

Probed the heuristic against live-style messages and fixed 6 real gaps:
- action verbs missed -ing forms ("TAG's been limping") → no READ
- the descriptor-subject regex required words between "the" and the noun, so
  "the whale called" missed → now handles bare "the <noun>"
- player departures ("TAG busted", "TAG left") weren't TABLE → added _DEPART
  (gated to non-first-person so "I busted, heading home" isn't a roster op)
- the bare word "stack" made strategy questions ("should I stack off?") classify
  as LOG → LOG now needs a number/result word AND excludes questions
- thin MENTAL lexicon → added coolered/sick/brutal/run bad/etc.

21-case probe (13 former misses + 8 regression guards) all green; folded into the
suite as 5 hardening tests. Full suite 201 green. classify() stays the swappable
seam for an LLM/MI50 upgrade later.
