[Feature Request]: Ability to specify files (such as JSON or CSV) to be exported to the Hop server.

### What would you like to happen?

Currently, if I use JSON or CSV files in a pipeline—even if they are located at the project root—they are not exported to the Hop server. It would be excellent to be able to specify, via the "RUN" configuration, that a specific file needs to be exported. This would simplify the workflow by eliminating the need to create a separate Docker image containing these files just to run the project on the Hop server.

Note: It would also be useful to be able to set a maximum size limit for files to avoid transferring large files.

### Issue Priority

Priority: 3

### Issue Component

Component: Infrastructure

Start by tracing how the RUN configuration handles files and how project assets are exported to the Hop server. Define how users specify JSON or CSV files and an optional maximum size, then verify that configured files are transferred without requiring a separate Docker image.
