fix(install): retry and auth github api downloads

Browse source 
.zinit-download-file-stdout made every request anonymously and gave
up on the first transient error. The gh-r test suite alone exceeds
GitHub's anonymous API limit of 60 requests/hour/IP, and racing CI
runs trip per-IP abuse throttling, failing whole zunit slices (run
33138613456: 28 failures, all rate-limited downloads).

Send Authorization from GITHUB_TOKEN/GH_TOKEN, strictly limited to
api.github.com so tokens never reach asset CDNs, mirrors, or snippet
hosts, and retry transient HTTP errors in curl and wget.
