Fixes #9: Parser performance optimizations
- Pre-compile all regex patterns as module-level constants in parser.js and jsonRepair.js - Add format detection caching (lastDetectedFormat, formatCacheHits) to skip redundant checks - Add clearFormatCache() export for cache invalidation - Add comprehensive test suite (33 tests) for parser and jsonRepair modules - Fix regex escaping in dynamic patterns (statRegex, fieldRegex) - Improve toFieldKey() regex specificity
