This week we completed the integration of the different Peras components in a temporary working branch. This large effort currently seats at +11,591/-3,754 LoC. Most of the speculative work is over, and we will start extracting meaningful PRs from this branch in the coming weeks.

More concretely, this week:

For the PerasEpochContextResolver (which is the stateful component allowing other components to access the proper PerasEpochContext given a PerasRoundNo), we removed the temporary wiring, and implemented proper ticking for it as part of the ExtLedgerState.
Merged bug-fixing #2029, and improved the voting thread to use the return status of the changed functions in its tracing.
Wired up the certificate extraction logic that pulls, validates, and potentially updates the latestPerasCertOnChainRound (which now lives on the ExtLedgerState) when a block containing a Peras certificate is received and applied onto the current ledger state.
Relatedly, we moved latestPerasCertOnChainRound method from the LedgerState to the ExtLedgerState; since we need ExtLedgerState data to validate incoming certs on-chain before updating latestPerasCertOnChainRound.
Various consistency improvements over Peras-related constraints in the codebase. The mega-classes BlockSupportsPeras and StateSupportsPerasEpochContext should be the main ones required in most components.
