Subject: [PATCH] Add /run command to execute prompts from files

New interactive command: /run <file-path>
- Reads the specified file and executes its content as a prompt
- Supports tilde expansion for home directory paths
- Behaves exactly like pasting the file content into the g3> prompt
- Shows helpful error messages for missing files or empty content
