1. Opens your browser to get an API key.
2. Validates the key you paste against the API.
3. Saves it to your shell config and ~/.scaledown/config.json.
4. Registers the MCP server with Claude Code.
5. Writes the UserPromptSubmit, PostToolUse and PreCompact hooks, the status line and the auto-compact threshold to ~/.claude/settings.json.
6. Offers to alias claude to dietcode claude, which turns on proxy mode.
7. Optionally configures Codex CLI and Cursor.
