- Fix PgQueryScanResult access to use result.pbuf.data
- Fix PgQuerySplitResult serialization with proper JSON and buffer management
- Disable deparse functions that depend on proto.js (temporarily)
- Remove proto.js from package.json files array
- Eliminate 5.4MB proto.js dependency completely

Addresses CI build failure: 'no member named pbuf in PgQuerySplitResult'

- Restore protobufCache mechanism for deparse without proto.js dependency
- parseQuery now caches protobuf data using WeakMap for automatic cleanup
- deparse retrieves cached protobuf data instead of using proto.js encoding
- Maintains all new functionality: normalize, scan, split, detailed parsing
- Keeps reorganized test structure and enhanced error handling
- Eliminates 5.4MB proto.js dependency completely

This reverts the deparse function to the working implementation that
successfully eliminated proto.js while keeping all other improvements.
