Introduce OmoVariant struct with STANDARD/SLIM constants to eliminate
~250 lines of copy-pasted code across DAO, service, commands, and
frontend layers. Adding a new OMO variant now requires only a single
const declaration instead of duplicating ~400 lines.
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
* feat(omo): integrate Oh My OpenCode profile management into Provider system
Adds full-stack OMO support: backend config read/write/import, OMO-specific
provider CRUD with exclusive switching, frontend profile editor with
agent/category/model configuration, global config management, and i18n support.
* feat(omo): add model/variant dropdowns from enabled providers
Replace model text inputs with Select dropdowns sourced from enabled
OpenCode providers, add thinking-level variant selection, and prevent
auto-enabling newly added OMO providers.
* fix(omo): use standard provider action styles for OMO switch button
* fix(omo): replace hardcoded isZh strings with proper i18n t() calls
