Add a per-instance local-player log prefix and apply it to networking and main plugin logs to make shared Fallout4Together.log entries readable when multiple instances run. Introduces F4T::Networking::GetLocalPlayerLogPrefix() (declared in F4TNetworking.h, implemented in F4TNetworking.cpp) and updates numerous REX::INFO/WARN calls to include the prefix. Also: only log sent player transforms after SendTransformPacket succeeds, add a small TODO comment about per-instance log files, and update docs (dev-log.md and plugin/setup.md) and the setup checklist to reflect the prefixed logging behavior. The prefix reads the assigned player ID via the thread-safe remote-player accessor and defaults to "[LocalPlayerId=unassigned]" before assignment.
