Research the end-to-end user experience of using Dev Proxy in a GitHub Codespace (as an app developer)

Investigate and document the step-by-step experience of an app developer using Dev Proxy within a GitHub Codespace (not working on Dev Proxy's codebase, but using it as a tool to assist app development). The research should cover:

- Codespace creation and startup, ensuring Dev Proxy can be set up as a runtime dependency or tool
- Guidance for installing, configuring, and running Dev Proxy in a Codespace terminal
- Usability of Dev Proxy's CLI for local app development in Codespaces (including port forwarding, networking, and integration with the user's app)
- How to use Dev Proxy to simulate API failures, throttling, and chaos for app testing
- Troubleshooting common issues specific to this workflow in Codespaces
- Recommendations for improving onboarding, documentation, or setup scripts for app developers

Deliverables:
- A documented E2E walkthrough (with screenshots or code snippets where possible) for an app developer
- A list of UX pain points and suggestions
- Recommendations for improvements
