yah-tower — rule-driven monitor on scryer (Phase 2).

This crate holds the rule engine: compiling TowerRule predicates to ScryerFilter shapes, parsing rules from YAML/JSON, and validating rules before they are loaded. The supervisor (F3), dispatch engine (F4), and trigger families (F5) will live here too when those tickets land.
