Function parseRenamedFilePath

vcs/git/git_stats.go:418–453

parseRenamedFilePath parses a renamed file path from git numstat output and returns the new (destination) file path. Handles two formats: 1. Full format: "old_path => new_path" (returns new_path) 2. Abbreviated format: "prefix/{old => new}/suffix" (returns prefix/new/suffix)

(filePath string)
