ci(nix): retry flake evaluation on GitHub API rate limits
Add a reusable retry helper that detects GitHub API 403 rate-limit errors
during Nix flake evaluation and retries with exponential backoff.

Apply the retry logic to flake-only CI tests so transient GitHub rate
limits no longer cause random CI failures while preserving fast failure
for real errors.
