This moves to Rust 1.86 as were prior on Rust 1.81, and the new alloy
dependencies require 1.82.
The revm API changes were notable for us. Instead of relying on a modified call
instruction (with deep introspection into the EVM design), we now use the more
recent and now more prominent Inspector API. This:
1) Lets us perform far less introspection
2) Forces us to rewrite the gas estimation code we just had audited
Thankfully, it itself should be much easier to read/review, and our existing
test suite has extensively validated it.
This resolves 001 which was a concern for if/when this upgrade occurs. By doing
it now, with a dedicated test case ensuring the issue we would have had with
alloy-core 0.8 and `validate=false` isn't actively an issue, we resolve it.
