vgsp-sema: keep the learned VA map across the session flush (re-compact, not wipe)
The flush fires when the channel table momentarily empties - a live
client's UVM channel cycling triggers it - and wiping the map left the
client's already-resolved data VAs unresolvable until a rebuild scan
re-found them, which it may not. Evidence: a mid-battery boot where
multikernel's operands went NO ENTRY 40+ s after a flush (the rebuild
restored 14-31 K entries without them); the pump stalled for minutes and
the next clients read back whole-page garbage. The map is a cache with a
merge-on-rebuild contract, so re-compact it (dedup + sort) and keep it as
the merge base; reused-VA correctness stays with the ledger landing, the
pin-wins rule and the fresh scan.
Also: push_battery.sh now pushes inplace_scale (the battery list had it,
the push list did not).
