Restore website link recovery window

[glenn-jocher]

Restore the intentional 30-minute delay between website link-check attempts so temporarily unavailable sites have time to recover. PR #358 incorrectly shortened this recovery window to 60 seconds while investigating a GitHub-hosted runner disconnect; the available evidence does not implicate the retry delay.

Keep the existing three retries and fixed backoff, and document the recovery window at its owner. Validation: actionlint and git diff --check pass. The completed four-site run in #358 already verified the unchanged scanning and reporting paths; this correction only restores the delay configuration.
