In the past, we used the `SR-Risk` and `C-Protocol-Critical` labels to require specific engineers to review PRs touching sensitive code:

- `SR-Risk` would tag @maurelian whenever legacy mainnet smart contracts were touched.
- `C-Protocol-Critical` would tag @tynes or @smartcontracts whenever smart contracts or `l2geth` were touched.

Since launching Bedrock, the `SR-Risk` label was removed from the `labeler` workflow, so it was never being applied. `C-Protocol-Critical` was still being applied, however it had no effect apart from blocking Mergify and pinging Mark/Kelvin unnecessarily since it is `CODEOWNERS` and not the label that prevents merge.

Given that we've started using `CODEOWNERS` and the fact that the labels were broken, this PR removes these legacy labels altogether.

contracts-bedrock: foundry-ify

op-challenger: Pass a context through to TraceProvider

feat(proxyd): sender rate limiter should check chain id

Will enable trace generation processes to terminate cleanly when op-challenger is shut down.

op-challenger: Add cannon-server and cannon-snapshot-freq flag

feat(op-challenger): GetOracleData call in Solver

The only thing that differs is the paths to the contracts

feat(op-challenger): Adds Preimage Data to the TraceProvider

Move the `contracts` directory to `src` and then move
the tests into a top level `test` dir so that its
standard foundry style for a repo.

This is going to break any in flight PRs so worth trying
to get in relatively quickly, will be no fun to rebase a
bunch of PRs.

Will need to follow up with another commit that bumps the
patch versions.
