Pull request overview

This PR upgrades nano-get to v0.3.0, expanding it into a more complete HTTP/1.1 GET/HEAD client with typed request/response APIs, optional HTTPS, proxy support, caching, authentication, and CI checks for compliance/coverage.

Changes:

• Reworks the core API surface (Url, Request, errors) and adds new modules for auth and HTTP-date handling.
• Adds extensive integration tests and runnable examples covering redirects, caching, auth, proxies, HTTPS tunneling, reuse/pipelining.
• Introduces CI workflows plus tooling to validate compliance docs and enforce line coverage.
