feat: Shadow Run Queue page (T06 template) — first KBX v60 page

Implement ShadowRunQueue.vue using KBX Foundation v60 components:
- T06 Queue template for job list display
- KbxScreenFrame wrapper with breadcrumb/title
- KbxSummaryBar showing job statistics (running/completed/failed)
- KbxTemplateStateBoundary for async state (loading/error/empty)
- Filter bar (search, status dropdown)
- Job items with progress bars, status tags, error messages
- Actions per job (view details, export, retry)
- Dark mode & responsive layout support

New files:
- features/shadow-run/pages/ShadowRunQueue.vue (page component)
- features/shadow-run/composables/useShadowRunJobs.ts (data fetch)
- features/shadow-run/types/index.ts (type definitions)

Updated:
- features/shadow-run/registry.ts (import ScreenDefinition from @kbx/contracts)

Demo data: 3 sample jobs (running, completed, failed) with realistic states.
Ready for API integration and production use.
