feat(storage): add MVCC historical reads, retention controls, and prune optimization

Add end-to-end MVCC storage support for nodes and edges, including committed
version records, persisted head metadata, snapshot-visible reads, and wrapper
delegation for namespaced, WAL, and async engines.

Expose MVCC retention controls through config and admin APIs, rebuild heads
during startup/restore, and add prune maintenance with safe tombstone
compaction and retained-floor anchoring to avoid post-prune historical lookup
cliffs.

Extend temporal procedures with optional system snapshot arguments, add
regression tests and benchmarks for MVCC visibility, pruning, and search
invariance, and document historical reads, retention knobs, and msgpack usage
through the user guides and operations docs.
