Add Kiai-decided metrics; keep Kiai at +2 (6.6, D47)

Report how often a Tecnica is played and how often Kiai decides a
Kumite or an Exam fight. The tie rule moves to RulesConfig.attacker_wins,
shared by the engine and the metric; games are unchanged. RULES.md drops
the Kiai +1 and catch-up variants from the rules under test.
