chore: bump nmtcpp to 2.1.0 by olyasir · Pull Request #1710 · tetherto/qvac

Summary

Bumps @qvac/translation-nmtcpp from 2.0.3 → 2.1.0
Cuts a release for the dynamic GGML backend loading feature shipped in QVAC-17129 feat: add dynamic backend loading to nmtcpp GGML backend for GPU acceleration #1617 (merged 2026-04-22)
Minor bump because QVAC-17129 feat: add dynamic backend loading to nmtcpp GGML backend for GPU acceleration #1617 adds new public config params (backendsDir, openclCacheDir) and unblocks Android GPU inference

CHANGELOG entry

## [2.1.0] - 2026-04-22

### Added

- Dynamic GGML backend loading for GPU acceleration. The NMT addon now discovers GGML backend plugins (OpenCL, Vulkan) at runtime via a new `NmtLazyInitializeBackend` singleton, mirroring the LLM addon's `LlamaLazyInitializeBackend` pattern.
- New `backendsDir` config param — points at the directory containing GGML backend `.so` plugins (e.g. the Android APK's native-lib path), unblocking GPU-backed inference on Android.
- New `openclCacheDir` config param — caches compiled OpenCL kernels for faster startup on subsequent loads.
- GPU backend `.so` plugins are installed into prebuilds via the `GGML_AVAILABLE_BACKENDS` CMake loop.

Test plan

CI (On PR Trigger (NMTCPP)) is green — in particular run-mobile-integration-tests / Build Android and Run E2E Tests (this is the regression we're cutting the release to fix)
Linux / macOS / Windows integration tests still green
iOS mobile still green
After merge: cut release-qvac-lib-infer-nmtcpp-2.1.0 branch and verify npm publish succeeds

Minor version bump for the new dynamic GGML backend loading feature (#1617) which unblocks GPU-backed inference on Android via `backendsDir` and adds `openclCacheDir` for faster OpenCL startup.
