+Prereqs: buzz binary on PATH (or BUZZ_CLI_PATH) — build with

+hermes secret from /home/opc/buzz-hermes-key.txt (already a relay + #general member).

+1. `~/.hermes/.env`:  `BUZZ_PRIVATE_KEY=<secret from /home/opc/buzz-hermes-key.txt>`
+2. Hermes `config.yaml`:
+   ```yaml
+   gateway:
+     platforms:
+       buzz:
+         enabled: true
+         extra:

+         require_mention: false   # trusted small circle; true = only @hermes
+         allow_all_users: true    # tiny private relay, everyone is known
+   ```
+3. `hermes gateway start` then `hermes gateway status`.
+4. Recommended display tweaks: `interim_assistant_messages: false`,
+   `tool_progress: off` under `display.platforms.buzz`.
+5. NIP-OA not needed (hermes pubkey is a direct relay member).
