Can take from swaps or block them, but cannot trap liquidity. Trade only through quotes that go on-chain.

• takes a cut of swaps
  The hook may add or remove value on every swap. Our fills for this pool come from the on-chain quoter, so whatever it takes is already in the number you see.
• controls pool creation
  Only pools the hook agrees to can be created with it — the launchpad pattern.
