Connect to multiple IRC servers concurrently from a single config file. Plugins are loaded once and shared; per-server state is isolated via separate SQLite databases and per-bot runtime state (bot._pstate). - Add build_server_configs() for [servers.*] config layout - Bot.__init__ gains name parameter, _pstate dict for plugin isolation - cli.py runs multiple bots via asyncio.gather - 9 stateful plugins migrated from module-level dicts to _ps(bot) pattern - Backward compatible: legacy [server] config works unchanged Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
