Changes: - remote_resolve_path.go: split filepath.Rel condition so that when filepath.Rel itself errors (rare, Windows-only), the error is wrapped with %w. The path-escape case (relativePath == "..") has no error to wrap so it keeps its original format. - remote_fetch_wasm.go: same split for the WASM build variant. - github_urls.go: wrap strconv.ParseInt errors in parseNumberedURL and parseRunURL, enabling errors.As(&strconv.NumError{}) by callers. - schedule_parser.go: split the strconv.Atoi+interval<1 condition in parseLongIntervalParts so that parse failures (non-integer input) wrap the underlying NumError, while the value-range check (interval < 1) keeps its original message. os.Stat errors are intentionally NOT wrapped to prevent *os.PathError from leaking into the user-facing error chain (enforced by TestUserFacingErrorsDontLeakInternals).
