Add xenia-ui crate; switch analysis store to DuckDB

Workspace gains a new xenia-ui member that owns the winit/wgpu
window, the Xenos display pipeline (xenos_pipeline + render +
texture_cache_host), HUD font/blit shaders, and the input-bridge
plumbing the app uses to surface guest framebuffers and overlays.

Workspace dependencies grow accordingly: rusqlite is replaced with
duckdb (analysis pipeline now writes DuckDB stores), and tracing /
metrics / pprof / winit / wgpu / gilrs / pollster / crossbeam /
bytemuck are added at workspace level so xenia-ui and xenia-app
share versions. Cargo.lock regenerated.
