Add core encounter processing pipeline

Filter by game version, parse levels and rate variants across all
generations, aggregate encounters by pokemon+method, and build
parent/child route hierarchy. Also completes encounter method coverage
(73/73) and pokemon form mapping (1180/1181) with manual overrides.
