Package ratelimitdemo is a small on-chain demo of the token-bucket rate limiter provided by the p/moul/x/daily/ratelimit(/p/moul/x/daily/ratelimit/v0) library.
It holds a single package-level ratelimit.Limiter and wires it to the chain: the tick is runtime.ChainHeight() and each caller is keyed by its address (unsafe.PreviousRealm().Address()). It contains no limiter logic of its own — refill/consume math all lives in the library.
Tokens reports how many whole tokens `addr` has available at the current block height, without mutating any state.
