[0.2.43] - 2026-04-10

Build System: Changed default library type from dynamic to static
- Default builds now produce static libraries (.a files)
- Shared libraries are only built when the dynamic-link feature is explicitly enabled
- Backend features (cuda, metal, blas, vulkan, etc.) no longer force shared library builds
- The dynamic-link feature can be combined with any backend feature to produce shared libraries
- Environment variable LLAMA_BUILD_SHARED_LIBS can override the default behavior

This change maintains backward compatibility for most use cases:

Applications using default builds will now get static libraries instead of dynamic ones
Applications explicitly using the dynamic-link feature will continue to work as before
All backend features (cuda, metal, blas, etc.) continue to work as expected
The LLAMA_BUILD_SHARED_LIBS environment variable provides an escape hatch for special requirements

If you were relying on the old behavior (dynamic libraries by default):

Explicitly enable dynamic-link feature:
```
cargo build --features dynamic-link
```
Or set the environment variable:
```
LLAMA_BUILD_SHARED_LIBS=1 cargo build
```

For Cargo.toml:

[dependencies.llama-cpp-sys-4]
version = "0.2.43"
features = ["dynamic-link"]

Smaller distribution size: Static libraries are self-contained
Easier deployment: No need to manage separate .dylib/.so files
Better compatibility: Static linking avoids library version conflicts
Explicit control: Developers can choose the linking strategy that best fits their needs
