Add first-login benevolence + sudo history context

- First-login benevolence hook on player join (once per player, persisted)
- New first-login memory file and config keys
- Benevolence command prompt enforces multi-command blessing behavior
- Limit first-login player-kill commands to at most one
- Add sudo history buffer (last 10 actions) and inject into sudo translator context
- Add effect syntax auto-fix for malformed 'effect <player> ...' outputs
