. Add token governance voting

[DeFiVC]

What: Add on-chain governance voting using token balances as voting power.

Why: Decentralized governance requires token-weighted voting. Important for protocol upgrades.

Scope: Add Proposal struct with description, choices, start/end time. Add create_proposal, vote, execute_proposal functions. Use token snapshots for voting power.

Acceptance criteria:

• Proposals can be created
• Token holders can vote
• Voting power is token-weighted
• Proposals can be executed

Technical context: contracts/learn-token/src/lib.rs — token functions.
