dev-python/fastsafetensors: add typer runtime dependency

All retained releases declare typer 0.9.0 or newer for their installed command-line
interface. Propagate it through the selected Python implementation.

dev-python/fastsafetensors: enforce setuptools floor

The exact 0.3.3 pyproject requires setuptools 78.1.1 or newer to build the native
extension. Preserve that requirement instead of relying on an incidental newer
backend.

dev-python/fastsafetensors: new package, 0.2.2

Tier 0 leaf for the vllm CUDA target packaging cycle. High-performance
safetensors model loader using NVIDIA GPUDirect Storage (CUFile) for
direct disk-to-GPU paths.

The C++ extension is built with pybind11 and links only against stdc++
— libcuda / libcudart / libcufile are dlopen'd at runtime through the
self-contained cuda_compat.h shim, so no CUDA headers are needed at
build time and no link-time CUDA dep. nvidia-cuda-toolkit is only
required to actually exercise the GDS path; the CPU fallback works
without it, so it is omitted from RDEPEND — the consuming vllm CUDA
target ebuild already pulls the toolkit.
