Merge feature/home-profile-restructuring: home-manager profile refactoring

Refactor home-manager configuration structure:
- Reorganize from features/ to base/coding/desktop/server/profiles/
- Add language runtime modules (go, js, python, rust, typescript)
- Add LSP server configuration
- Add gaming and media profiles
- Add shell modules (fish, nushell, starship)
- Consolidate editor and git configuration
