- Refactor the semver inspector so that it can be called from outside the CLI
- Adds a a canonical L2 genesis file for v1.6.0, and a unit test to assert that new chains deployed using v1.6.0 have the right L2 genesis.

* removing duplicate default bootnode

* adding conduit bootnodes

* removing duplicate bootnode

* use a queue.Queue for channelBuilder.frames

* remove pop and push terminology

* proliferate queue.Queue type

* simplify requeue method

* undo changes to submodule

* sketch out new arch

https://www.notion.so/oplabs/op-batcher-re-architecture-114f153ee162803d943ff4628ab6578f

* add TODO

* add channelManager.pruneSafeBlocks method and integrate into main loop

* fix frameCursor semantics

* fixup tests

* avoid Rewind() in tests

* only rewind cursor in rewind (never move it forward)

* fix assertions

* prune channels whose blocks are now safe

* handle case when rewinding a channel with no blocks

this is strange, I don't think we should expect channels with frames but no blocks...

* add clarification

* implement channelManager.pendinBlocks() method

* fix pruning logic

* simplify pruneChannels

* simplify pruneSafeBlocks

* add unit tests for pruneSafeBlocks

* fix pruneSafeBlocks to avoid underflow

* improve test

* add unit tests for pruneChannels

* introduce handleChannelTimeout

and simplify channel.TxConfirmed API

* factor out channelManager.rewindToBlockWithHash

* change test expectation

* do more pruning in test

* Replace "clean shutdown" behaviour with waitNodeSync()

Instead of optimizing for a clean shutdown (which we couldn't guarantee anyway), this change optimizes for code simplicity.

This change also helps us restrict the amount of code which mutates the channelQueue (removePendingChannel was doing removal of channels at arbitrary positions in the queue).

The downside is that we may end up needlessly resubmitting some data after the reset.

Reorgs are rare, so it makes sense to optimize for correctness rather than DA costs here.

* Add readme and architecture diagram

* don't panic when there is a safe chain reorg

* fix test

* readability improvements

* only clear state after waiting for node to sync

* resize image

* tweak readme

* typo

* rewindToBlockWithHash never moves cursor forward

* use s.pendingBlocks()

* add log line

* check there are blocks when handling timeout

* rename HasFrame() to HasPendingFrame()

* fixup test

* improve readme

* link to open issues by tag

* add log when main loop returns

* pass blockID to rewindToBlock

and panic if block does not exist

* don't remove all channels when a channel times out

keep older channels, it's possible that they also time out

* use newSafeHead.L1Origin in Clear() when pruning blocks

* clarify comment

* use warn log level on safe chain reorg pruning, and unify handling for safe head above unsafe head

* update panic message

* extend test coverage and fix bug

* rename test blocks

* simplify HasPendingFrame() method

* simplify implementation of RewindFrameCursor

* activate dormant test

* ensure pending_blocks_bytes_current metric is tracked properly

* cover metrics behaviour in test

using new TestMetrics struct

* extend test coverage to channelManager.handleChannelTimeout

* add comment to TxFailed

* rename test fn

* point to e2e tests in readme.

* readme: performance -> throughput

* improve channel_manager_test to assert old channels are not affected by requeue or timeout

* fix handleChannelTimeout behaviour

We were trimming older channels and keeping new ones. We need to trim newer channels and keep old ones. Fixes associated test (see previous commit).

* tighten up requirements for invalidating a channel

* replace requeue with handleChannelInvalidated

* op-batcher: fix channel duration timeout management

Previously, we would use L1 data to help track channel durations. For example, the batcher would be configured to post data every hour. We update a global state variable with the latest l1 origin of a channel when it closed, and compute the deadline for that channel using a duration delta starting at that l1 origin timestamp.

Since we changed the way autoDA switching works, a channel can be _closed_ (due to a duration timeout or other reason) and this will cause the l1 origin state variable to move forward, extending the deadline ready for the next channel. Crucially, with autoDA switching nowadays, the closed channel will not always be submitted on chain (it can be discarded and the blocks requeued). If it is discarded, the channel duration timeout has already been extended.

The fix for this is to update the global state variable at channel submission time, not channel closing time.
