Changes

Nargo.toml Updates

All contracts now use the shorter aztec-nr dependency format:

# Before
aztec = { git = "https://github.com/AztecProtocol/aztec-packages/", tag = "...", directory = "noir-projects/aztec-nr/aztec" }

# After  
aztec = { git = "https://github.com/AztecProtocol/aztec-nr/", tag = "v3.0.0-devnet.6-patch.1", directory = "aztec" }

Package.json Updates

All npm dependencies updated to 3.0.0-devnet.6-patch.1

API Fix

Fixed test-wallet-webapp to use the new cast_vote signature:

// Before
cast_vote(1n)

// After
cast_vote({ id: 1n }, 1n)
