- Needed to add ekubo and uniswap v4 to callback-limited protocols.
- I had to bump the fork block in all of our integration tests: The way it was before meant that certain integration tests were using certain executor addresses, and others were using different ones, because of the redeployment. This was a pain to account for on the rust side. Instead, all tests now use an Ekubo-compatible fork block. Values needed to be updated because of price changes between blocks.
Only the first swap of a SwapGroup would actually get a transfer in, so we don't need to do this inside of the swaps loop
Rename in_token and out_token to token_in and token_out in SwapGroup

In both encoding and contracts:
- Make sure that the tests names/encoder match what is happening (we had test_split_... that was only a single swap).
- Made modules inside the encodings tests
- In swap_encoders: there is one module per protocol
- In strategy_encoders: there is one module per strategy and an extra protocol_integration module. Inside the sequential module there is another module called chained_swaps
- In contracts, each strategy has its own file. Integration tests per strategy should also be here. Renamed TychoRouterIntegration to TychoRouterProtocolIntegration. Only protocol integration tests should be in this file

ENG-4327 Took 1 hour 13 minutes
- In Tycho Router
- Fix integration tests
- If the trade is cyclical, we can't do the balance check for the correctness of the amountOut transfers
- In encoding,
- if it is a wrap trade, the transfer should be just a normal Transfer (not TransferFrom nor a Permit2Transfer)
- add test names to println! statements

Add transfer in Executor and pass receiver address in encoding
This is done by using the TAKE action instead of TAKE_ALL

Add transfer in Executor and pass receiver address in encoding
Remove integration test with StETH pool because we don't support it at simulation level and there is something weird with the amounts (that it is not worth it to investigate now)

- The out transfer is now a responsibility of the Executors -> remove this from router methods
- Also adding a check that the receiver got the full amount out
- In encoding, if it is the last swap, pass the receiver as the trade receiver and not the router address (fix encoding tests)
- Fixed some solidity tests (after rebasing with a PR that is still open, I will fix them all)

- This needed to be in BalancerV2 so that the executor can also take care of transfers from the user into the tycho router, to avoid having transfer actions mixed between the router and executors
- This needed to be in Curve so that the executor can also take care of transfers from the user into the tycho router, to avoid having transfer actions mixed between the router and executors
- For protocols like Balancer and Curve, which expect funds to be in the router at the time of swap, we must support also transferring funds from the user into the router. Doing this in the router would mean we are dealing with transfers in two different places: in the router main methods and in the executors. To avoid this, we are now performing transfers just in the executors, and two transfer types have been added to support transfers into the router.
TODO:
- Add this for Balancer and Curve (only added for USV4 atm).
- TODO consider renaming TRANSFER_FROM and TRANSFER_PERMIT2 to include "pool" in the name
- Also do some renamings and comment improvements:
transfer method -> type
- Remove integration tests since we no longer support direct calls to USV3 executor, even for testing.
- For now, hardcode them to TRANSFER on the rust encoder side. This will be fixed in an upcoming PR.
- Remove the split swap simple route integration test - seemed overkill since simple routes are tested in many other integration tests, the original rust test named doesn't exist anymore, and simple routes should anyway be passing through the single endpoint.
- The tycho router address default is set at the EncoderBuilder level (not inside the strategies)
- Rename TychoCoreChain to TychoCommonChain
- Only take TychoCommonChain as an argument at the outermost level: EncoderBuilder. Everywhere else we use the execution Chain right away

We have a trait TychoEncoder and then two implementations: TychoRouterEncoder and TychoExecutorEncoder.
This way we go a level above with the decision if it is a direct execution or if it should use the tycho router.
- Created two builders: one for each tycho encoder
- Delete ExecutorStrategyEncoder and move code straight into the TychoExecutorEncoder
- Add validate_solution to trait TychoEncoder
- Move group_swaps.rs a level up
- Update tests and usage cases
Doing this we get rid of all that weird stuff we were doing before
