fix(ci): trigger plugins on rust changes, add ldconfig for nllb cache hits

- ci.yml: add rust filter to plugins job condition so changes to
  plugin SDK (sdks/**) or core crates (crates/**) trigger plugin
  linting — prevents breaking SDK changes from going undetected
- plugins.yml: add ldconfig step for CTranslate2 cache hits,
  matching the sherpa-onnx pattern for consistency
