- Renamed ExecutorTransferMethods to TokenTransfer to avoid leaking information about how the transfer happens into the executor. The executor shouldn't care if there are multiple methods or one single method that takes care of everything.
- Also renamed TransferMethod to TransferType to match the rust encoding
- This arbitrary sender should be same, since the sender is always set to be msg.sender from within the contract (no calldata can be sent specifying otherwise). This is just used to circumvent msg.sender being the pool/protocol during callbacks.
- 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.
- Properly decode, update tests with proper decoding
- Added test case for each transfer method
- Also fully tested permit2 transferFrom and it works perfectly.
NOTE:
UniswapV3 doesn't support NONE as a transfer method.
TODO:
- Fix integration tests once encoding is implemented.

- 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

ENG-4332 Took 1 hour 10 minutes
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

- Had to take the implementation of the swap header encoding out of the main EVMStrategyEncoder trait, since it will now be difference for single and split swap strategies.
- Integration tests will be added in separate task/PR.

- Need to manually install foundry and compile the project, or else it attempts to install the latest foundry version, which fails due to GLIBC not being found
- Add more test cases for sequential swap and single swap to match those of split swap (fee, slippage), to catch errors more easily if someone makes a small code change to either the single or sequential methods
- Excluded USV3 and USV4 tests on sequential and single swap, since these tests were more to test USV3 and USV4 executor functionality than the high level sswap methods - they should already be sufficiently tested.
- Remove `testSplitSwapSimple` and `testSplitSwapSingleUSV3` since this is already tested by several other high-level methods (see single USV3 and single USV4 tests). We should prioritize integration-testing public methods over private methods.
- The old way was useful when we just had split swaps. Unfortunately, we now have split, sequential, and single swaps, which don't always require token indices or split percentages, so we need to decode differently for each case.
- Add some basic tests (will add more in next commits)
- Adapt sequential tests (which originally tested split swap)
- Adapt a forgotten single swap test
TODO:
- Fix encoding of single and sequential swaps to not expect the split sawp format every time (the split and the token indices are not necessary and consume unnecessary gas).
