execute_proposal succeeds with zero votes -- no quorum or minimum vote check

[DeFiVC]

What

execute_proposal (learn-token lib.rs:1701) does not check if any votes were cast. If no one votes on a proposal, all vote_totals are 0, and the function still marks the proposal as executed with winning_choice = 0 and winning_votes = 0.

Why

A proposal that received zero votes should not be executable. This allows an admin to create a proposal, wait for the voting period to end, and execute it with a "winner" that no one voted for. This undermines the governance mechanism.

Scope

Add a check after the tally loop (after line 1725):

if winning_votes == 0 {
    panic!("no votes cast");
}

Acceptance Criteria

• execute_proposal panics if no votes were cast
• Test verifies zero-vote proposals cannot be executed

Technical Context

• contracts/learn-token/src/lib.rs:1701-1733 -- execute_proposal
• contracts/learn-token/src/lib.rs:1716-1725 -- tally loop (no quorum check)

Hello! I’d be happy to contribute to this task.

I’m comfortable picking up unfamiliar codebases, tracing existing behavior, and making focused changes without disrupting other functionality. I’ll take ownership of the implementation from understanding the requirements through testing and final verification.

I’d appreciate the opportunity to work on it.

Hi maintainer,I'd like to take this issue, Here's my solution as the issues asks:

I’ll add a guard in "execute_proposal" after the tally loop to reject proposals with zero votes, using the specified "no votes cast" panic. I’ll also add a regression test confirming that a zero-vote proposal cannot be executed.

Please assign to me I'll start immediately and open pr within 24 hours
