These are no longer used, in favor of the `op-node` commands
that generate the genesis files instead.

contracts-bedrock: delete imports

feat(ctb): make StandardBridge vars immutable

chore: Upgrade foundry

Updates the StandardBridge to use immutable variables instead of state
variables. Primary reason for this change is to guarantee that the
storage layout will not be a problem during the upgrade. Plus, there's
really no reason why these variables shouldn't be immutable.

Use `hardhat compile` so that it ensures that the artifacts
used by the generator are up to date

Moves the `GovernanceToken` into `contracts-bedrock`
so that its artifact can be easily inspected. This
is the first step in deleting `contracts-governance`.
The other files should be moved to `contracts-periphery`.

Every L2 predeploy that has `Semver` must be built so that it's
immutables are handled, even though they are hardcoded in the
bytecode.

Copies the implementation from upstream
https://github.com/ethereum/go-ethereum/blob/389021a5afd01147c851870c693ded8760e6a08c/internal/ethapi/api.go#L1149

MetaMask requested that we use ethers submodules instead of importing
the entire ethers package. Relatively straightforward change.

Fixes two contracts in contracts-periphery to use the correct import
paths. Also modifies the contracts package to copy contracts into the
root directory on every build, not just before publish. This resolves
the issue where the contracts package could not be properly used within
the monorepo.

Last unwrapped errors

These where missed in local lints but when a full lint was run these
popped up.

* op-node: Properly wrap errors

* op-proposer: Properly wrap errors

* Update linters to use errorlint

This includes a hack with golangci-lint to disable the assertion
and comparison check in errorlint but to retain the errorf lint.

In the the future the assertion lint could probably be fixed, but
the comparison lint may be overactive with certain cases.

* op-node: Properly return error on bad hex data

* Add forgotten err to Pub2PeerID

* op-node: Switch to 128 bit channel ID & block # timeout

This PR removes the 256 bit channel ID + timestamp. With the timestamp
being removed, the channel timeout is now done with block numbers.

* Update specs/derivation.md

* fix system test config

* op-node: Fix OPB-01

`(*ExectionPayload).UnmarshalSSZ()` fails to properly validate the `transactionsOffset` and `extraDataOffset` values, allowing a malicious actor to crash multiple op-nodes by gossiping a P2P message containing a specially crafted `SSZExecutionPayload`.

* lint

- OPB-05: Puts the signature verification before further unmarshaling to guard against mal-formed payloads.
- Adds a minimum size check to the payload decoding to ensure we always have at least a signature and a payload available.
