Postmany reads filenames from stdin and transfers file content to/from an HTTP(S) endpoint.

It is designed for event-driven pipelines where a list of files is produced by one tool and streamed to another system.

• Stream filenames from stdin
• Upload with POST or PUT
• Download with GET
• Multiple worker fibers (-w) for concurrent transfers
• Static request headers (-H) for APIs like Azure Blob
