The implementation of this CEP adds the ability to plug-in custom compressors providers
which might delegate the de/compression to a specialized hardware. An operator does not
need to change any schema definition, the mere implementation of a compressor provider
put on a class path and its related configuration in cassandra.yaml will transparently
start to use appropriate compressor, e.g. backed by a specialized hardware.

When BTreeRow.merge reconciles an update into a row whose existing deletion
shadows the update's cells, it filtered the update (incoming) side of the merge
with Reconciler.retain, which records the removal via
PostReconciliationFunction.delete. On the memtable write path that subtracts the
shadowed cells' on-heap size from the allocator's ownership even though that
incoming data was never allocated to the memtable. Under overwrite/delete churn
that re-applies cells already covered by a newer row/partition deletion (e.g.
repair re-streaming), the allocator's "owns" counter drifts negative and the next
flush trips "AssertionError: Negative released" in MemtablePool$SubPool.released
via MemtableAllocator$SubAllocator.releaseAll during discard.
Filter the update (incoming) side with a non-recording variant,
Reconciler.removeShadowed, and keep retain() for the existing side,
whose data the memtable already owns. The filtered result is identical; only the
erroneous accounting notification is dropped. This mirrors the already-correct
complex-column path in ColumnData.merge.

CommandChanges.shouldCleanup short-circuits to NO if there is no data, but this is incorrect as Cleanup.EXPUNGE may have dropped the data and the record must receive cleanup EXPUNGE and be reported as ERASED.
Also Fix:
- Populate CFK system table row markers so we can stop reading sstables as soon as we have data
- system_accord_debug.executors has wrong clustering type
- RemoteToLocalVirtualTable should lazily allocate the partition collector to avoid LIMIT clause filtering removing it before it's populated
- ActiveEpochs.withNewEpochs should handle transition from 0 -> more than 1
- RedundantBefore.minGcBefore should be NONE if empty
- Update RangesForEpoch directly, so that we cannot have race conditions where the ownership is unknown
- Avoid reentrancy on local callbacks
- Ensure ReadCoordinator callbacks are invoked on owning thread
- Avoid deadlock when notifying ComplexListener(s)
- Release IntrusivePriorityHeap memory from large capacity heaps when empty
- Prevent SynchronousRecoverAwait reentrancy when invoking onDone (by exposing and invoking invokeOnDone that first sets isDone)
- maybeExecute must invoke either notWaiting or notifyWaiting to ensure tryExecuteListening terminates
Also Improve:
- Configurable execute_waiting_on_start

Wires the conventional AGENTS.md -> SECURITY.md -> security model chain so automated tooling
can mechanically discover the project's security model. No model content is changed.
