+
+### Added
+
+- **VERSION export** - Package version is now exported from index.ts, automatically read from package.json
+
+### Changed
+
+- 🔄 **Refactored SecretDetector** - Reduced cyclomatic complexity from 24 to <15:
+  - Extracted helper methods: `extractByRuleId`, `extractAwsType`, `extractGithubType`, `extractSshType`, `extractSlackType`, `extractByMessage`
+  - Used lookup arrays for SSH and message type mappings
+- 🔄 **Refactored AstNamingTraverser** - Reduced cyclomatic complexity from 17 to <15:
+  - Replaced if-else chain with Map-based node handlers
+  - Added `buildNodeHandlers()` method for cleaner architecture
+
+### Quality
+
+- ✅ **Zero lint warnings** - All ESLint warnings resolved
