> Following the implementation of standard HMAC-SHA256 payload verification, this task extends the functionality to support the STREAMING-AWS4-HMAC-SHA256-PAYLOAD-TRAILER algorithm.
> When a client uploads a file with trailing checksums (e.g., x-amz-checksum-crc32c), S3G must not close the stream immediately after receiving the 0-byte final chunk. Instead, it must continue to parse the trailing headers and verify the x-amz-trailer-signature to ensure the integrity of the appended checksums.
