WASM DB for fast in-browser calcs

We tried to push a large dataset through our browser-based tool and the old JS engine just died. Swapping in DuckDB compiled to WebAssembly turned out to be the fix.

Now the whole analytical DB runs client-side. Parsing, filtering, and aggregation happen in the browser, so no network latency or server round-trips. Performance is surprisingly solid: multi-hundred MB CSVs load in a couple seconds and queries scale up without the UI locking.

Feels like a big unlock for building heavier analytics directly on the client. If you want to join us, we are Datastripes
