Description: PR summary This PR introduces the foundational OverlayManager to backend_bases.py, setting up the architecture required for high-frequency interactive overlays (like cursors and crosshairs) without triggering expensive background redraws. Key Changes: Added OverlayManager to manage registered overlay artists using weak references. Attached OverlayManager to FigureCanvasBase initialization. Implemented Phase 1 (Fallback Mode): Standard canvases automatically fall back to setting animated=False on artists and routing redraws to draw_idle(). Added unit tests in test_backend_bases.py to verify the fallback behavior, registration logic, and a future-looking test (currently marked XFAIL) for native compositing in Phase 2. Addresses #30515 . AI Disclosure AI tools were used to assist in drafting text and suggesting validation scenarios. All code changes, final implementation decisions, and verification were done manually. PR checklist "closes #0000" is in the body of the PR description new and changed code is tested Plotting related features are demonstrated in an example New Features and API Changes are noted with a directive Documentation complies with guidelines
