Migrating to v0.5.0

This release includes breaking changes:

• netutil.CleanString was removed. Map spaces/controls yourself, or use SafeFileName for filenames.
• Prefer netutil.SafeFileName over deprecated SafeURL (output may differ: filepath.Base, extension-preserving truncate).
• DownloadFileToLocal accepts HTTP 200 only, caps at 500MB, and uses a 30s timeout; use DownloadFileToLocalLimit for other size limits.
• netutil HTTP helpers (Get, PostJson*, PostForm*) use a 30s default timeout.
• Pool SubmitErr returns sentinel errors: use errors.Is(err, lutil.ErrQueueFull) / ErrPoolClosed instead of matching error strings.
