Module stream_priority_scheduler 

Stream-level priority scheduler for multiplexed network streams.

Implements multiple scheduling disciplines:

• Strict Priority (SP): highest-priority streams always scheduled first
• Weighted Fair Queuing (WFQ): proportional share based on weight
• Deficit Round Robin (DRR): byte-accurate fairness with deficit counters
• Earliest Deadline First (EDF): deadline-aware scheduling for latency-sensitive flows
• Hierarchical Token Bucket (HTB): hierarchical bandwidth allocation with token buckets

All methods are no_std-friendly (no external crates beyond what’s already in Cargo.toml).
