Subject: [PATCH] Persist FPS slider and Enter Play Mode dropdown across editor
 restarts

ToolbarFPSSlider:
- Mark selectedFramerate [SerializeField] (default 60) so the chosen
  value survives domain reload / editor restart.
- Replace global GUI.changed with EditorGUI.BeginChangeCheck/EndChangeCheck
  to avoid reacting to unrelated GUI events.
- Save() the toolbar setting on change so toolbar-side edits are persisted
  even when the Project Settings panel is not open.

ToolbarEnterPlayMode:
- Mark selectedEnterPlayMode [SerializeField] as a defensive cache.
- Lazy-init enterPlayModeOption labels in OnDrawInToolbar in case the
  initializer hasn't run yet.
- Apply selection to EditorSettings via a dedicated helper, called both
  on Init() and on user change, so the saved value is enforced on
  editor open.
- Switch to BeginChangeCheck/EndChangeCheck instead of GUI.changed.
- Save() the toolbar setting on change.
