This commit introduces a comprehensive set of improvements to the error handling and loading mechanism of the WebAssembly (WASM) module. The key changes include: - **Structured Error Handling:** Replaced generic string-based errors with a structured `WasmError` type in the Go WASM wrapper. This provides standardized error codes (`bad_request`, `not_found`, `conflict`) and clear messages, allowing JavaScript clients to handle errors programmatically. - **Isomorphic WASM Loader:** Refactored the JavaScript loader (`loader.js`) to be isomorphic, enabling it to run seamlessly in both browser and Node.js environments. The loader now detects the environment and uses the appropriate mechanism for loading the WASM binary and `wasm_exec.js`. - **Type Conversion Fix:** Resolved a panic (`panic: ValueOf: invalid value`) that occurred when returning `[]float64` slices from Go to JavaScript. A new `pointToJS` helper function now correctly converts these slices to `[]any`, ensuring proper data marshalling. - **Improved Smoke Test:** Enhanced the WASM smoke test (`smoke.mjs`) to verify the new structured error handling and to correctly handle the API's response format. - **Configuration Updates:** Updated the `.golangci.yml` configuration to be compatible with the latest version of `golangci-lint`. In addition to these changes, this commit also includes a new `AUDIT-ERROR-HANDLING.md` file, which documents the findings of a thorough audit of the project's error handling and logging practices.
