Rules v0.8: Fatica on crossing, no Kumite in round 1, board draft 2

- Fatica costs a stripe for every Fatica walked onto; a route whose Fatica
  drops a Brown player below 15 no longer enters the Dojo
- No Kumite in the first round: opponents are treated like meditating pawns
- Board draft 2: two Fatica tolls per quadrant, Allenamento moved to the ring
- Casual bot, --summary-csv, per-seat breakdown and move-options metric
- Out of contention measured at 3 belts
- Plan: Phase 6 baselines, decisions D34-D43
