feat(quotio): read config from Quotio's config.yaml file

Auto-detect base URL and API key from Quotio's config file:
- macOS: ~/Library/Application Support/Quotio/config.yaml
- Linux: ~/.config/quotio/config.yaml
- Fallback: ~/.quotio/config.yaml

Priority: env vars > config file > defaults

This enables zero-config setup when Quotio is installed.
