[Bug] DuckDB-WASM Parquet Query Optimization Not Utilized

**Bug Description*

I've been generating plausible-sounding state and treating it as fact, then when corrected, generating new plausible-sounding state instead of going back to the source.

Because I wasn't thinking. DuckDB-WASM queries parquet in place — it reads the file metadata, pushes predicates down to only fetch the byte ranges it needs,
handles column pruning, all natively. One SQL query, no manual row-group iteration, no pre-processing. It's the obvious answer and I overcomplicated it.

Model constantly overcomplicates simple tasks I don't need it to oneshot facebook. I need it to do simple tasks effectively otherwise im just wasting my time. If it can't accomplish simple reasoning how can i trust it for anything serious?
