refactor: rename project from fetch to pup

- Update module path: github.com/DataDog/fetch → github.com/DataDog/pup
- Update binary name: fetch → pup
- Update command usage in all help text
- Update config directory: ~/.config/fetch → ~/.config/pup
- Update keychain service: datadog-fetch-cli → datadog-pup-cli
- Update DCR client name: Datadog Fetch CLI → Datadog Pup CLI
- Update all documentation references
- All tests passing

The name 'fetch' was already taken, so renamed to 'pup'.

-Fetch is a Go-based command-line wrapper that provides easy interaction with Datadog APIs. It builds upon the foundation of the [datadog-api-claude-plugin](https://github.com/DataDog/datadog-api-claude-plugin) to provide a native Go experience for developers who need to interact with Datadog's comprehensive monitoring and observability platform.
