Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify all references to @tsconfig/node22 have been replaced with @tsconfig/node24 across all package configurations
• Confirm @types/node version is consistently set to 24.9.0 or 24.9.2 across the monorepo
• Check that engine requirement changes (contracts and simulator packages) are intentional and appropriate for downstream consumers
• Validate CHANGELOG.md accurately reflects all version updates and package modifications

Poem

🐰 From twenty-two to twenty-four we hop,
With tsconfigs updated, the versions don't stop!
Node types reimagined, a fresh TypeScript breeze,
The engines now humming a new-versioned tease,
Our monorepo's upgraded—hooray and huzzah! 🎉
