Function normalizePath

internal/services/orphanscan/filemap.go:111–125

normalizePath cleans and normalizes a path for consistent comparison. Uses filepath.Clean (OS-specific separators) and NFC unicode normalization to avoid mismatches between canonically-equivalent strings (e.g. composed vs decomposed forms on some platforms). Tradeoff: canonically-equivalent names co

(path string)
