Contract
- Req interpolates colon-style and curly-style path parameters with URI encoding while leaving unmatched path segments intact
- assert passing an integer range sets the Range header to bytes=first-last while string ranges pass through unchanged
- assert matching response body SHA-256 succeeds while a mismatched checksum raises Req.ChecksumMismatchError with expected and actual fields
- assert Req.Test stubs handle json helper responses and simulate transport errors when retry is disabled
- assert setting raw: true preserves the unparsed response binary rather than decoding JSON
