What

• Bumps soroban-env-host-prev to P22 and -curr to P23
• Splits the GoLedgerStorage trait implementations for Protocol 22 (which uses SnapshotSourceWithArchive) and Protocol 23 (which just uses SnapshotSource)
• Introduces a new, optional parameter to simulateTransaction:

interface SimulateTransactionRequest {
  authMode?: "" | "enforce" | "record" | "record_allow_nonroot"
}

which explicitly allows users to opt-in to non-root authorization in recording mode.

The behavior rules are:

• default (omitted): enforce if auth entries are present, record otherwise (the behavior today)
• enforce: always enforcement mode, even with an empty list
• record: always recording mode, failing if any auth exists
• record_allow_nonroot: like record but allowing non-root authorization

Why

Handle the breaking changes across the Protocol 22 and 23 simulation libraries cleanly.
Add non-root simulation support for both protocols per #344.

Known limitations

Integration testing isn't possible without an accompanying Core build.
