AZIP-1: Reduce Governance Execution Delay to 2 Days

[just-mitch]

Summary

• Introduces AZIP-1, a proposal to reduce the governance execution delay from 30 days to 2 days
• The current 30-day delay doesn't achieve L2Beat classification benefits while hurting protocol development velocity and sequencer capital efficiency
• Rollup-specific protections should be handled by a dedicated gating contract (AZIP-2) rather than inflating the global governance delay
