chain-kpis: add polkadot (DOT native, Asset Hub stables)#1191
Merged
Conversation
Ships live KPIs on /chains/polkadot. DOT price and mcap flow through Mobula. Stables card renders via DefiLlama Asset Hub aggregate. TVL and DEX gauges stay unpublished (relay chain has zero DeFi: parachain TVL lives under Acala, Moonbeam, Hydration). Also guards defillama TVL publish to skip zero values so chains that DefiLlama tracks by name but with an all zero series (Polkadot today) hide the TVL card instead of rendering $0.

Summary
Adds Polkadot to the chain-kpis harness registry so
/chains/polkadotrenders a live KPI strip like every other chain page. Also guards the DefiLlama TVL publish to skip zero values.Behavior

Any chain that DefiLlama tracks by name but with a legitimately zero TVL series will now hide the card instead of surfacing a broken looking "$0".
