/**
 * @title AereGovernor
 * @notice A standard, audit-ready OpenZeppelin Governor for AERE Network.
 *
 *         Unlike the deployed AereGovernanceStaked (which executes via
 *         address(this).call on opaque data, owns nothing, and reads a
 *         deprecated staking contract that reports zero stake), this Governor:
 *           - executes arbitrary (target, value, calldata) batches THROUGH a
 *             TimelockController with an enforced delay (binding, not theatre);
 *           - reads a CHECKPOINTED IVotes source (AereStakedGovVotes) so voting
 *             weight is snapshot-fixed and not flash-stake borrowable;
 *           - counts votes with the standard For / Against / Abstain module,
 *             simple-majority pass rule, and a quorum expressed as a fraction of
 *             the votes token's past total supply.
 *
 *         It is deliberately a plain OZ Governor so it can be externally audited
 *         against a well-known reference before it is ever granted authority
 *         over anything of value.
