Replace custom extension.ts initialization and agent-based routing with
csc's built-in registerBundledSkill({ files }) mechanism. Review and
security-review skills are now registered with embedded files that
get lazily extracted to disk on first invocation. Locale is resolved
at startup via getResolvedLanguage().
- Remove agent generation from generate-review-builtin.ts (skill-only)
- Remove extension.ts, REVIEW_AGENTS registration, strict:* skills
- Add reviewSkills.ts with registerReviewSkills() for unified registration
- Adapt to new costrict-review index.json format (skills-only, new paths)
- Remove src/costrict/command/locales/ (no longer needed)
