I am also wondering if it would be worth having the module output something that could be used by a coder_app resource to provide a dynamic live preview based on the detected project type.

You already have a check for verifying that there is a running app as a result of the module running at the end of run.sh

I think what you should do is take this and set the project port to a local which you could then use in a coder app resource to set a preview app for this module.

You could also set a variable to disable this feature in the module if you would like, but I think this would fit perfectly in this module with this logic.

IE..

resource "coder_app" "preview" {
  count        = var.enable_preview_app ? 1 : 0
  agent_id     = coder_agent.dev.id
  display_name = "Live Preview"
  url          = "http://localhost:${local.detected_port}"
  # other configuration...
}

This looks great! the only thing you might want to point the coder app icon to an actual existing icon or emoji in coder.
