The rule that runs replace_issue_labels safely

replace_issue_labels stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Forgejo, apply this rule, and every replace_issue_labels call is checked against it from then on.
