fix(windows-release): bundle sherpa-rs runtime DLLs in zip + installer

The Windows zip and NSIS installer previously shipped only clx.exe +
clx-screen-reader.exe. clx.exe depends on sherpa-onnx-c-api.dll,
onnxruntime.dll, onnxruntime_providers_shared.dll and cargs.dll, all of
which sherpa-rs's build.rs drops into rs/target/release/. Without them,
clx.exe fails at launch with STATUS_DLL_NOT_FOUND (0xC0000135) and no
stdout/stderr — leaving users with a silently-broken download.

- release-rust.yml: copy *.dll from rs/target/release/ into both the zip
  staging dir and the NSIS staging dir. Fail the build if no DLLs are
  found (guards against sherpa-rs build.rs regressions).
- installer.nsi: File "*.dll" to include every staged runtime DLL, and
  matching Delete "*.dll" in uninstall.

Verified on a Windows 10 22H2 box: dropping sherpa-onnx v1.10.34 shared
DLLs next to clx.exe lets the process start cleanly in session 1.
