PR Summary

Medium Risk
Medium risk because it removes a previously selectable log format and associated tests/CI configuration, which may impact builds or deployments that still reference V3 settings.

Overview
This PR removes the experimental Log V3 surface area and standardizes the codebase on DbLogFormat.V2 only.

It deletes the ExperimentalV3 option from DbLogFormat, drops the V3 node creation path in ClusterVNodeHostedService (now throws if anything but V2 is configured), and simplifies scavenge support flags/messages.

Tests/CI are updated to stop targeting or filtering V3: V3 TestFixtures and V3-specific conditional assertions/setup are removed, EventStore.LogV3.Tests is dropped from scripts/test.sh, the V3 test filter is removed from ci.runsettings, and the Microsoft.FASTER.Core package reference is removed.
