Module cloud 

Cloud-native I/O abstractions for OxiGDAL streaming.

This module provides pure-Rust abstractions for cloud object storage:

• Parsed cloud URLs (S3, GCS, Azure, HTTP/HTTPS)
• Byte-range request building and HTTP Range header generation
• Object metadata representation
• Cloud credentials (anonymous, access key, service account, Azure, bearer)
• Presigned URL generation (AWS SigV4 / GCS v4 — pure-Rust HMAC-SHA256)
• Multipart upload state tracking and XML generation
• Range coalescing for efficient cloud reads
• Retry policy with exponential back-off and jitter
