The rule that runs editor_patch_apply safely

editor_patch_apply 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 010 Editor, apply this rule, and every editor_patch_apply call is checked against it from then on.
