The rule that runs wa_send_poll safely

wa_send_poll 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 WA MCP, apply this rule, and every wa_send_poll call is checked against it from then on.
