rootandClaude Opus 5.5 e994a7bcfa feat(domain): rule groups — MP rule-string parser/serializer, builtin keywords, chain evaluation wired into slot
- rules/: RuleExpr tree, '>' layers with ! & | and parens, position-aware errors
  (unknown atom with suggestions, unsupported music atoms, parens, empty layer)
- builtin keyword table aligned with MP BUILTIN_RULE_SET; field-based judgement
  where parsed fields exist, MP regex otherwise; custom atoms (MP 7 fields)
- chain evaluation: hard excludes, ladder pri 100-k, groups AND-ed, pri from last
  laddered group, readable per-atom trace
- slot: SlotSpec.rules, rule.hard_exclude / rule.no_layer_matched violations,
  pri basis switches to priority when a rule ladder is present
- differential: 66 rule chains x 32 torrents vs MP python path (parse 64/64,
  pri 2090/2112, 22 registered mp_bug)
