llvmlite is trying to build an old version that creates a dependency chain issue when installing with uv:
```
help: `llvmlite` (v0.36.0) was included because `vibevoice` (v0.0.1) depends on `librosa` (v0.11.0) which
depends on `numba` (v0.53.1) which depends on `llvmlite`
```
pinning these dependencies on newer versions forces it to resolve and shouldn't have any downsides.
