Release/node/v0.5.3

Changed

• Optimize QUIC for high latency links
• Keep permanent ADNL validator keys

[Copilot]

Pull request overview

This PR updates the node’s QUIC transport behavior for better performance on high-latency links, and adjusts validator key rotation/cleanup to avoid removing still-referenced ADNL keys. It also bumps the node crate version to 0.5.3.

Changes:

• Switch QUIC transport to use BBR congestion control and remove the extra per-connection stream semaphore, relying on QUIC transport limits instead.
• Update validator key revision logic to keep ADNL keys when they’re still referenced by other elections (and adjust pruning threshold).
• Update QuicNode::new call sites for the constructor signature change, and bump versions.
