Greptile Summary

This PR adds a docstring to universal_router_execute, appends # NOTE: lines inside two existing docstrings, clarifies inline comments in the multi-action test, replaces hardcoded ABI type strings with centralised v4_actions_abis lookups, and removes the unused gas positional parameter from _get_tx_params.

• uniswap4.py: ABI strings for SETTLE_ALL/TAKE_ALL switch from the hardcoded uint128 to the centralised uint256 definition (ABI-encoding-identical for in-range values); the dead gas=250000 parameter is dropped from _get_tx_params; two # NOTE: lines are embedded literally inside docstrings.
• tests/test_uniswap4.py: Explanatory comments are added around the commands/actions/params setup, but one comment incorrectly states WRAP_ETH has "1 action" when it is given an empty list (0 actions).

Confidence Score: 4/5

Safe to merge — all changes are documentation and minor refactoring with no functional regressions.

The ABI refactoring is correct and the gas parameter removal is clean since it was never read by the function body. The only concrete mistakes are a contradictory comment in the test and # NOTE: lines embedded as literal text inside docstrings, both of which affect readability rather than runtime behaviour.

The two comment/docstring issues are in tests/test_uniswap4.py (wrong action count) and uniswap/uniswap4.py (# NOTE: inside docstrings); no other files need attention.
