feat(omo): add OMO Slim (oh-my-opencode-slim) support

Implement full OMO Slim profile management to align with ai-toolbox:
- Backend: Slim service methods, DAO, Tauri commands, plugin conflict handling
- Frontend: types, API, query hooks, form integration with isSlim parameterization
- Slim variant: 6 agents (no categories), separate config file and plugin name
- Mutual exclusion: standard OMO and Slim cannot coexist as plugins
- i18n: zh/en/ja translations for all Slim agent descriptions
