name: Context7 refresh

# Listens for completion of "Update version tags" via workflow_run, then
# refreshes the corresponding Context7 variant. The upstream workflow is
# matched by name — DO NOT rename `Update version tags` without updating
# the `workflows:` field below.
#
# OPERATOR NOTE: do NOT use GitHub's "Re-run jobs" on `Update version tags`.
# Re-runs replay the original SHA, which would move the version tag
# BACKWARD and trigger this workflow to refresh Context7 against stale
# content. To force a Context7 refresh, use the workflow_dispatch input
# below — it calls Context7 directly without touching any tag.
