feat(dirol): add Dirol Aggregator contract address

[dak-agent]

Adds a Dirol Aggregator contract to mainnet/dirol.jsonc:

• Aggregator: 0x646462f4d0168A94fE1884c8ae82148a3618A18d

Evidence: BlockVision curated label "Dirol / Aggregator" (verified) for this address on Monad mainnet; Dirol is a live meta-DEX aggregator (dex.dirol.io, DefiLlama). Distinct from the existing CoreAggregator. Surfaced during the activity-dashboard top-contracts attribution review (rank #127).

python scripts/validate_protocol.py --network mainnet --protocol dirol passes.
