perf: trim zip features, optimize frontend minification, fix Windows CI

- zip: disable default features, use only deflate-zlib (drops 11 crates:
  zopfli, zstd, bzip2, lzma, deflate64, xz2 — unused since we only read
  WebXDC archives, never write them)
- terser: passes 3, pure_getters, toplevel mangle (49.7% reduction, +4%)
- CI: shorten CARGO_TARGET_DIR on Windows to avoid MAX_PATH limit in
  whisper.cpp's Vulkan shader generator CMake ExternalProject build
