Pull request overview

This PR addresses a crash in the LoadPacks RPC flow by resetting state that can otherwise retain stale pointers across RPC invocations, aligning with the goal of reloading packs without fully clearing the pack registry.

Changes:

• Clear the cached m_loadedPacks collection before reloading packs to avoid retaining dangling RtePackage* pointers.
• Clear the global RTE model in the LoadPacks RPC handler before reinitializing and loading packs.
