docs(roadmap): mark plural rules engine tasks as done/in-progress

- Add PluralValidationReport with missing/have sets
- Add collect_resource_plural_issues and Codec::collect_plural_issues
- Refactor validate_plurals to fold reports into an Error

- Per-language counts of entries with missing plural categories
- Total missing plural categories per language

- Resource-level: autofix_fill_missing_from_other_resource
- Codec-level: autofix_fill_missing_from_other
- Skips DoNotTranslate entries; sets NeedsReview when autofilling
