Put back to draft because I recalled that changing jsconfig to tsconfig breaks import of types from JS files. for example this becomes any:

dapp-treasury/ui/src/types/types.js

Lines 162 to 165 in 2f02253

	/**
	* @typedef { import('@agoric/run-protocol/src/vaultFactory/vaultManager').AssetState } AssetState
	*/

)

Closing in favor of investing in dapp-inter
