[aofei]

No description provided.

PR Overview

This PR corrects the usage of gop.Project in main.go by updating the server initialization and file conversion logic, and it adds a new build step for WASM in the CI workflow.

• Update server initialization to use gop.NewProject with the appropriate parameters.
• Change the conversion function to return a pointer to vfs.MapFileImpl instead of a struct value.
• Add a new "Build WASM" step in the CI configuration.

• Ensure that changing the MapFile construction to a pointer of MapFileImpl is consistent with downstream code expecting vfs.MapFile. Verify that this change does not introduce nil pointer issues in parts of the codebase that use these files.

result[key] = &vfs.MapFileImpl{

.github/workflows/go.yml:28

• Verify that the build.sh script exists and has executable permissions so that the new WASM build step in CI does not fail.
