[None][doc] Add overlap scheduler pipeline diagram

[Satyamkale123]

Description

The Overlap Scheduler section explains how GPU forward passes for step N+1
run concurrently with CPU result processing for step N, but the concept is
described only in text and code.

This diagram provides a visual timeline showing the GPU/CPU overlap pattern,
making it easier for new contributors to quickly grasp the pipelining strategy
that enables higher throughput.

Changes

• Added overlap_scheduler_pipeline.png to docs/source/media/
• Updated docs/source/features/overlap-scheduler.md to include the diagram

Type of change

• Documentation update

Dev Engineer Review

• Added overlap_scheduler_pipeline.png to the documentation media directory.
• Embedded the diagram in overlap-scheduler.md.
• The diagram shows concurrent GPU forward passes and CPU result processing.
• No code, API, configuration, or test-list changes require review.

QA Engineer Review

No test changes.

Approving — the comments below are optional touch-ups, not blockers.

Diagram is accurate and legible, and it matches the text and code snippet below it. Two small things:

• The SPDX header isn't mentioned in the description and isn't part of adding a diagram. If you keep it, use 2026 to match the convention in docs/source/features/model-express.md rather than 2022-2026 (this file wasn't created in 2022).
• No source file for the PNG is checked in, so the next person to edit it has to redraw it. See the inline note.
