Improving .replit File Editing Convenience

Replit has been using the .replit file for project configuration, but previously there was the inconvenience of having to check external documentation to understand how to configure it.

Now, with the introduction of Taplo (an LSP server for TOML), users can take advantage of intelligent code completion and documentation features when editing .replit files directly within the workspace.

The development team implemented this efficiently by using Go's jsonschema module to generate a JSON Schema from the field tags of existing Go structs, without needing to modify the structs themselves.

In particular, for the Command type, which can take various forms such as string, array, or object, the team went through a technical optimization process, including developing a custom schema generation function to provide accurate documentation and schema support.
