/**
 * @title ZEUSGovernorSimple
 * @dev Non-upgradeable Governor contract for ZEUS Pepes Dog Community Take Over (CTO) DAO
 *
 * This contract manages the entire proposal lifecycle for the ZEUS DAO,
 * allowing wZEUS token holders to create proposals, vote, and execute
 * governance decisions through a Timelock.
 *
 * Configuration:
 * - Voting Delay: 1 block (~12 seconds)
 * - Voting Period: 50,400 blocks (~1 week)
 * - Proposal Threshold: 4,206,900,000,000 wZEUS (1% of ZEUS total supply)
 * - Quorum: 1% of wZEUS supply
 * - Timelock Delay: 86,400 seconds (1 day)
 *
 * Features:
 * - Updatable settings via governance (voting delay, period, threshold, quorum)
 * - Simple counting (For/Against/Abstain)
 * - Timelock integration for secure execution
 * - Non-upgradeable (immutable)
 *
 * Proposal Lifecycle:
 * 1. Created → 2. Active (after 1 block) → 3. Voting → 4. Succeeded/Defeated
 * 5. Queued (in Timelock) → 6. Executed (after 1 day delay)
