sync-status: add cosmos/CometBFT handler (gaiad + cosmos batch)

Browse Source 
Cosmos-hub has NO EVM RPC — eth_blockNumber checks don't apply. Add a --cosmos
handler that probes the CometBFT /status method: sync_info.catching_up=false =>
online, else syncing; optional head-gap check vs the drpc reference. sync-status.sh
dispatches protocol=cosmos -> check-health.sh --cosmos. eth/starknet/aztec untouched.
