Update src/ai-repo-commander.user.js

handleSuccess() now handles list_files by extracting a files array from typical n8n payloads and pasting a neat text code block. If it can’t find a files array, it pastes the raw JSON so you can see what came back.

Added auto-submit after paste (AUTO_SUBMIT: true). It:

tries clicking a visible Send button (button[data-testid="send-button"] or aria-label*="Send"),

falls back to synthesizing Enter key events.

Added APPEND_TRAILING_NEWLINE: true (helps some editors pick up a final input change reliably).

Removed the unused scanExistingMessages() and updated a comment in the parser to match actual behavior.
