vicrodh c8ef2a1b1d 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.

# QBZ Slint — FAST dev build/run (DEBUG, *not* release).
#
# ADDITION to ./slint-dev.sh, NOT a replacement. Use this for quick, purely
# visual / layout iteration where runtime performance does NOT matter — it is
# dramatically faster to compile than the release build because:
# - debug profile (opt-level 0) → the giant Slint-generated module skips the
# heavy LLVM optimisation passes that dominate the release build,
# - the `mold` linker (much faster than the default `ld`),
# - NO debuginfo (`-C debuginfo=0`) → less to generate AND less to link,
# - the nightly PARALLEL FRONTEND (`-Z threads`) across cores.
# Debug builds live in target/debug, separate from the release target/release,
# so the two scripts don't invalidate each other's cache.
#
# DO NOT use this to judge performance — the binary is unoptimised. Always do a
# final pass with ./slint-dev.sh (release) before trusting runtime behaviour.
#
# RUSTFLAGS overrides .cargo/config.toml, so the AES-NI/SSSE3 features are
# re-listed here (keep in sync with slint-dev.sh / .cargo/config.toml).

# Usage: ./scripts/slint-dev-fast.sh [extra cargo args]
# THREADS=22 ./scripts/slint-dev-fast.sh # override frontend threads
