* op-supervisor: Introduce head tracker

* op-supervisor: Move log db to subpackage of db.

* op-supervisor: Route all updates through a common db that can track heads

* op-supervisor: Remove unused error.

* op-supervisor: Remove operations - it fits into a later PR.

* op-supervisor: Fix semgrep

* op-supervisor: Move resuming databases into ChainsDB so it can later update the chain heads too.

* op-node: sequencer / engine events refactor

incl sequencer events fixes

* op-node: distinguish block sealing error kinds

* op-node: review fixes, stashed tweaks

* op-node: events based sequencer chaos test

* op-node: fix missing DerivedFrom data in attributes test

* op-node: drop old wip debugging work log

* op-node: sequencer move OnEvent function

* op-node: update stale todo comment

* op-node: detect derivation block-building as sequencer, and avoid conflict

* op-node: clarify comments and rename PayloadSealTemporaryErrorEvent to PayloadSealExpiredErrorEvent to describe applicability better

* op-node: prevent temporary engine error from influencing inactive sequencer

* op-supervisor: Move TruncatedHash and ExecutingMessage out of db package

* op-supervisor: Introduce EntryIdx type

Will make it clear when a value is a block number vs a db entry index when adding head tracking.

Ensures the database is rewound to the point where it can retry storing the logs for the block rather than having some logs already exist.
