webpack: Add sql-wasm.js to CopyWebpackPlugin to fix 404 error

- Root cause: sql-wasm.js file exists in node_modules but not copied to build output
- Error coming from sql-wasm.js:159 indicates missing file on deployed site
- Added sql-wasm.js to CopyWebpackPlugin patterns to copy it to build output
- Updated debug memory with root cause analysis

 - `981.js` was fixed but there's another file (`870.js`) still trying to load from root path
 - Found the same pattern in `870.js`: `locateFile:t=>".././sql-wasm.wasm"`
 - Webpack plugin is working but not catching all files
+- **ROOT CAUSE FOUND**: Error is coming from `sql-wasm.js:159` - this is a separate `sql-wasm.js` file that's being loaded dynamically
+- The `sql-wasm.js` file exists in node_modules but is NOT being copied to build output
+- **SOLUTION**: Add `sql-wasm.js` to CopyWebpackPlugin to copy it to build output
 
 ## Files Found
 - ✅ `981.js` - Fixed (path changed from `.././sql-wasm.wasm` to `./sql-wasm.wasm`)
-- ❌ `870.js` - Still has `.././sql-wasm.wasm` pattern
+- ❌ `870.js` - Still has `.././sql-wasm.wasm` pattern (webpack plugin not processing distribution files)
+- ❌ `sql-wasm.js` - Missing from build output, needs to be copied by webpack plugin
 
 ## Next Steps
 1. Update webpack plugin to catch all chunk files including 870.js
