chore: add voting token with balance 1

[ctrlc03]

Fixes deployed demo on sepolia, where it is not possible to vote because of balance mismatch (crisp app hardcodes 1, and the backend creates the tree using the actual token balance)

Summary by CodeRabbit

• New Features

  • Added a mock voting token with per-address balance caps.

• Updates

  • Reduced minted token amount in the mint flow.
  • Improved voting flow to avoid stale callbacks.
  • Deployment/config updated to use a unified mock flag and to support mock token deployments.
  • Added mock deployment entries and helper scripts.

📝 Walkthrough

Walkthrough

Adds a mock ERC20 (MockVotingToken) with per-address cap, consolidates mock deployment flags into USE_MOCKS and updates deploy scripts/records, reduces client mint amount from 1e18→1e9, and adds getMerkleLeaves to a voting hook dependency to avoid stale closures.

Changes

Cohort / File(s)	Summary
Client Hooks examples/CRISP/client/src/hooks/generic/useMintToken.tsx, examples/CRISP/client/src/hooks/voting/useVoteCasting.ts	Mint amount reduced from BigInt(1 * 1e18) → BigInt(1 * 1e9); added getMerkleLeaves to a useCallback dependency array in useVoteCasting
Smart Contracts (Mocks) examples/CRISP/packages/crisp-contracts/contracts/Mocks/MockVotingToken.sol	New ERC20 mock MockVotingToken with MAX_BALANCE = 1e9, constructor mints 1e9 to deployer, public mint(address,uint256) that mints capped amount (silent no-op if cap exceeded), and decimals() override returning 18
Deployment & Packaging examples/CRISP/packages/crisp-contracts/deploy/crisp.ts, examples/CRISP/packages/crisp-contracts/deployed_contracts.json, examples/CRISP/packages/crisp-contracts/package.json, examples/CRISP/packages/crisp-contracts/.env.example, examples/CRISP/scripts/crisp_deploy.sh	Replaced USE_MOCK_VERIFIER/related flags with unified USE_MOCKS; conditionally deploys MockVotingToken and records MockCRISPToken in deployed_contracts.json; added deploy:contracts:mock script and updated mock deploy invocations and env example

Poem

🐇 I hopped a build and minted small,
A capped token answers voting's call.
Flags combined, deployments sing,
Merkle leaves now wake on spring.
Tiny hops, big changes — CRISP for all! ✨

In `@examples/CRISP/packages/crisp-contracts/deploy/crisp.ts`:
- Around line 29-43: The MockVotingToken deployment is not waited on, so the
blockNumber captured in storeDeploymentArgs may be before the tx is mined;
update the MockVotingToken deployment code (where you call
ethers.deployContract('MockVotingToken')) to call and await the
contract.waitForDeployment() before calling token.getAddress() and before
calling storeDeploymentArgs (using the same pattern as other deployments like
ZKTranscriptLib/RiscZeroGroth16Verifier), and also make the network name
derivation resilient by replacing the existing chain lookup with a safe fallback
using (await owner.provider?.getNetwork())?.name ?? "localhost" so chain is
never undefined.

🧹 Nitpick comments (2)

examples/CRISP/packages/crisp-contracts/deploy/crisp.ts (1)

117-117: Avoid logging undefined token address when mocks are off.
Line 117 prints TokenAddress: undefined when USE_MOCKS is false; consider guarding the line or logging a clearer message.

examples/CRISP/packages/crisp-contracts/contracts/Mocks/MockVotingToken.sol (1)

16-29: Use MAX_BALANCE constant and fix the stale comment.
Line 16’s “half of 10e18” doesn’t match 1e9, and 1e9 is repeated in constructor/mint. Consider using MAX_BALANCE to avoid drift.

♻️ Suggested refactor

-  // half of 10e18
+  // Cap per address for mock voting power
   uint256 public constant MAX_BALANCE = 1e9;

   constructor() ERC20("Mock Voting Token", "MVT") {
-    _mint(msg.sender, 1e9);
+    _mint(msg.sender, MAX_BALANCE);
   }

   function mint(address to, uint256) external {
-    if (balanceOf(to) + 1e9 > MAX_BALANCE) {
+    if (balanceOf(to) + MAX_BALANCE > MAX_BALANCE) {
       // silently fail
       return;
     }
-    _mint(to, 1e9);
+    _mint(to, MAX_BALANCE);
   }
