- 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).
Rollback some of the Ekubo's Executor changes to a previous version to use the generic callback logic using transient storage
Took 1 hour 25 minutes
Took 13 seconds
After a callback is performed, the executor address transient storage is set to 0 so that multiple callbacks can't be performed for the same swap

- Created methods to deploy the router and the executors. Whenever we use rollFork we need to redeploy everything! Notice that the addresses will be different then!
- Created a test_executor_addresses.json to be used in the encoding tests, this way the calldata for the integration tests is already correct and we don't need to do any manual replacing (this was annoying). The addresses in this file match with the addresses used in the solidity tests

With this, we don't need the univ3 specific method in the router contract. This should be flexible enough for most protocols that integrate
TODO: is this safe enough??

This way we can define protocol and chain specific addresses in this file and use them in the Encoders

Curve pools use a different address from ETH (native token)
- Pass Chain into the SwapEncoderBuilder and SwapEncoder
- Add native_token_curve_address and native_token_address to CurveSwapEncoder
- Added integration test for this curve case

We don't know the pool tokens in the ProtocolComponent, so we can't infer the indexes correctly. Added a call to the MetaRegistry curve contract to get the correct token indexes. To do this, I had to move the get_client to utils. We could actually refactor the transaction logic into its' own struct and use it here and in the approval logic
It was assumed that all the pools will have a "factory" static attribute, even if empty

We don't need to use all the functionalities of the Curve Router, only the swap type 1 (exchange). By bypassing the router we can save gas on 2 token transfers and with smaller calldata
A nice side effect is that the executor is much more readable and understandable now
