Networking & Chunked Transfer Implementation

[itsyashvardhan]

Implement the core networking layer for FLUX:

• Use Python sockets to enable peer-to-peer file transfers with support for TCP (UDP optional for future stretch goal)
• Support multi-threaded upload/download with concurrent chunked streaming for large files (>10MB)
• Allow configurable chunk size via GUI and command options
• Integrate retry/backoff logic to handle packet loss and intermittent network failures
• Provide mechanisms for resuming interrupted transfers using chunk tracking/hash verification
• Ensure IRC-like pipeline for concurrent chunk transfer.
