refactor: migrate hardcode detector from regex to AST-based analysis

- Replace regex-based matchers with tree-sitter AST traversal
- Add duplicate value tracking across files
- Implement boolean literal detection
- Add value type classification (email, url, ip, api_key, etc.)
- Improve context awareness with AST node analysis
- Reduce false positives with better constant detection

Breaking changes removed:
- BraceTracker.ts
- ExportConstantAnalyzer.ts
- MagicNumberMatcher.ts
- MagicStringMatcher.ts

New components added:
- AstTreeTraverser for AST walking
- DuplicateValueTracker for cross-file tracking
- AstContextChecker for node context analysis
- AstNumberAnalyzer, AstStringAnalyzer, AstBooleanAnalyzer
- ValuePatternMatcher for type detection

Test coverage: 87.97% statements, 96.75% functions
