chore: merge develp code to main for release v0.5.6

[joeylichang]

v0.5.6

This is a minor release for opBNB Mainnet and Testnet.

It includes several performance optimizations and improvements, primarily focused on transaction pool enhancements and block mining efficiency.
Key improvements include tuning snapshot bloom filters for higher TPS, optimizing block mining overhead with a new engine API, and multiple transaction pool optimizations such as cache management, truncation efficiency, direct transaction broadcasting, stale transaction filtering, and asynchronous pricing.
Metrics have also been added to monitor these optimizations.

Upgrading is optional.
