Round 1 findings and fixes, all previously uncommitted: - FXProcessor per-slot DSP history repair (HEAD does not compile without it) - SynthVoice::getModulationValue, editor control-lock guard - ExactCompare.h naming the deliberate exact float comparisons - KnobLookAndFeel replacing the never-installed SerumLookAndFeel - 55 first-party compiler warnings to 0 - AGENT.md renamed to AGENTS.md across Source/ - graft repository context graph and its hooks - JANITOR_TASKS.md and UI_UX_AUDIT.md records
