refactor(slint): split qbz-slint into qbz-ui lib + qbz bin; reclaim qbz binary

Slint cannot split the .slint compilation across crates, but a Slint LIBRARY
crate exposes its generated Rust types to dependent crates (verified with a
minimal proof). So:

- NEW crate `qbz-ui` (lib): owns the whole .slint tree + build.rs + bundled
  translations; `slint::include_modules!()` + the generated types (AppWindow,
  MiniPlayerWindow, all globals/structs) are re-exported. Translation domain is
  now `qbz-ui` (the .po files renamed accordingly).
- `qbz-slint` (bin) -> renamed to `qbz` (package + `[[bin]] name = "qbz"`),
  reclaiming the binary name from the retired Tauri app. It depends on `qbz-ui`
  and does `pub use qbz_ui::*;` so existing `crate::AppWindow` / `crate::*State`
  references resolve unchanged.

This splits the single ~20 GB rustc into two crates (UI/codegen vs the 75k LOC
of logic) — the foundation for lower build peak, incremental caching, and the
upcoming per-feature crate extraction.

Also fixed for the move: qbz-i18n bundled-.po include paths, the font/WGSL
`include_bytes!`/`include_str!` paths (-> ../../qbz-ui/ui/), workspace members,
dev scripts (`-p qbz`), and the CI workflows. `cargo check -p qbz` is green.
