clique_propose(address, true) from an existing validator starts the voting process to add a new one.

Requires >50% of current validators to vote yes — strict majority rule.

Three validators: need 2 votes (>50% of 3) to approve any change.

Voting is on-chain — no need to modify genesis.json or restart nodes.
