RiskyMH 7ccb1a5ebe Add comprehensive node:sqlite implementation with advanced features
- Implement core DatabaseSync and StatementSync classes
- Add support for all Node.js sqlite constructor options
- Implement advanced statement features:
  * sourceSQL and expandedSQL properties
  * setReturnArrays() for array-based results
  * setReadBigInts() and setAllowBareNamedParameters()
- Support all parameter binding types (positional, named, object)
- Add comprehensive test suite with 10+ test files
- Fix memory issues in location() method with proper CString handling
- Add missing sqlite3_local.h include for compilation
- Achieve 85-90% Node.js API compatibility
