Implement Automated Contract Upgrade Testing and Validation

Priority: High
Estimated Time: 2.5 hours

Description

Contract upgrades are manual and risky. Automated testing of upgrades would prevent breaking changes and data corruption.

Tasks

• Implement upgrade_simulation_tests.rs that tests upgrade path
• Verify: state is preserved, old match data is accessible, fees are correct
• Add upgrade compatibility checks (same storage keys, same function signatures)
• Run upgrade tests in CI on every contract change
• Add upgrade testing guide to docs/upgrade-safety.md
