AI Summary

Monad v0.13.0 release activates MONAD_NINE with three major improvements: MIP-3 implementing linear memory, MIP-4 introducing a reserve balance precompile with multiple refinements, and MIP-5 adding the Osaka fork's CLZ opcode. The release also includes several robustness fixes for race conditions and internal optimizations.
