All 5 upptime-driven workflows (graphs / response-time / static-site /
summary / uptime) call api.github.com for releases lookup + issue
management + result commits. Post the 2026-05-06 GitHub org
suspension, no token in our org authenticates there anymore — every
scheduled run fails with HTTP 401 "Bad credentials".
Move the workflow files to .github/workflows-disabled/ so Gitea
Actions stops scheduling them. Adds a README explaining what
happened and pointing at #2 for the replacement plan
(Gitea-native uptime probe).
The history/ directory and .upptimerc.yml stay untouched — the
existing probe-list config is still useful as input to the
replacement; the historical JSON files are read-only data we may or
may not migrate forward.
Tracked: #2.
