Critical: Change file.stream({start,end}) → file.createReadStream({start,end})
to match real webtorrent ^2.5.1 API (WHATWG ReadableStream vs Node Readable).
Important #1: RFC 7233 compliance — clamp end >= total to total-1 instead
of rejecting with 416. Only reject when start >= total or start > end.
Important #2: Attach stream error handlers to prevent unhandled crashes
on peer disconnect or missing pieces.
Minor: Add tests for range clamping (bytes=50-999999 on 100-byte file)
and out-of-range fileIdx. All 6 tests passing (green).
