feat: initial whatsmeow bot with command handler and context helpers

Core framework (Handler, Command, Default muxer) in core/ package. Command self-registration via init() with blank imports in cmds/. Context helpers (send, reply, download, upload) in context/ package. Permission system with GROUP_ONLY / PRIVATE_ONLY checks. WhatsApp client configured as Safari with history sync disabled.
