Detect Uniswap V4 hooks whose address-encoded permission flags don't match the callbacks the hook actually implements. In V4 the hook's permissions live in the low bits of its deployed address (mined via CREATE2 salt) and must agree with getHookPermissions(); a callback the hook implements but whose flag bit is unset is never invoked, and a flag set without a real implementation makes pool initialization revert in Hooks.validateHookPermissions. Activate on any BaseHook/IHooks contract, getHookPermissions overrides, or hook address mining.
