refactor: enhance YAML with regex patterns and inline arrays

- Add pattern key with original fuzzy regex from scriptregex.mjs
- Rename abbreviations to alt for brevity
- Convert to inline YAML arrays for compactness
- Migrate full pre/post rules to shared/en.yml
- Add LDS-specific pre_rules for JST handling
- Update jest config to exclude _archive directory
- Update test to use new alt key
