Port Go server/subject_transform.go to .NET. Implements a compiled transform engine that parses source patterns with wildcards and destination templates with function tokens at Create() time, then evaluates them efficiently at Apply() time without runtime regex. Supports all 9 transform functions: wildcard/$N, partition (FNV-1a), split, splitFromLeft, splitFromRight, sliceFromLeft, sliceFromRight, left, and right. Used for stream mirroring, account imports/exports, and subject routing.
