Change -Suffix parameter in Create-Clip.ps1 from optional empty string to required non-empty string with default value "-Clip", removing the hardcoded "-Clip" prefix from target name derivation so suffix is inserted directly before extension (e.g. default behavior unchanged: P01.mp4 -> P01-Clip.mp4, but custom -Suffix "-Shot-1" now makes P01.mp4 -> P01-Shot-1.mp4 instead of P01-Clip-Shot-1.mp4), add ValidateNotNullOrEmpty attribute, update documentation to reflect new default and behavior, and add installation

## rife-ncnn-vulkan
To install rife-ncnn-vulkan on Windows, download it from [rife-ncnn-vulkan](https://github.com/nihui/rife-ncnn-vulkan) and add it to your system PATH.
To install rife-ncnn-vulkan on Windows, see the [RIFE 4.26 installation guide](RIFE.md). Add it to your system PATH.

## NCNN_GPU_ID
The environment variable **NCNN_GPU_ID** is used to specify the GPU device ID for ncnn-based applications.
This environment variable must be set for both `rife-ncnn-vulkan` and `upscayl-bin`.
The value stored in **NCNN_GPU_ID** will be either:
- **`0`** — use the first Vulkan-capable GPU (device index 0). If you have multiple GPUs, they'd be `0`, `1`, `2`, etc.
- **`-1`** — use CPU only (no Vulkan GPU is available).
These map directly to the `-g` flag values accepted by both `rife-ncnn-vulkan` and `upscayl-bin`:
| `-g` value | Meaning |
| --- | --- |
| `0` | First GPU |
| `1` | Second GPU |
| `2` | Third GPU |
| `-1` | CPU |
