Contract: Add governance vote validation for policy changes

[Junirezz]

Summary

Policy updates should only pass when governance rules are satisfied.

Problem

Governance paths may not clearly validate required conditions before state updates.

Acceptance Criteria

• Require valid quorum and state checks for policy changes
• Reject invalid or stale governance proposals
• Add tests for under-voted or mis-timed changes
• Document governance state machine assumptions
