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

 .SYNOPSIS
     Creates a new clipped video file using Clone-Video.ps1, requiring the -Video and -Frames parameters.
-    The filename used for the -Target parameter is automatically derived from the -Video filename, with "-Clip" inserted before the video file extension (e.g., P01.mp4 becomes P01-Clip.mp4).
-    When the video name carries a '.skip' marker before its extension, "-Clip" is inserted before that marker so it stays last (e.g., P01.skip.mp4 becomes P01-Clip.skip.mp4).
+    The filename used for the -Target parameter is automatically derived from the -Video filename, with the -Suffix value (default "-Clip") inserted before the video file extension (e.g., P01.mp4 becomes P01-Clip.mp4).

     Any extra parameters will be pass directly to Clone-Video.ps1, except for parameters -Video, -Frames, -Suffix and -Target.
 .PARAMETER Video
     Path to the input video file. Can be absolute or relative to current directory. If the path has no extension, .mp4, .webm and .mkv are tried in turn.

 .PARAMETER Suffix
-    Optional text appended to the derived -Target name after "-Clip" and before the file extension
