docs: add initial roadshow presentation outline

[gdemonc]

Summary

Prepare the presentation outline for the roadshow deck.

This PR focuses on organizing the presentation structure and aligning the high-level storyline for the PPT, so the team can continue filling in detailed content and visuals on top of a clearer narrative frame.

Changes

• add the initial roadshow presentation outline
• structure the deck flow by major presentation sections
• clarify the main storytelling order for the presentation
• provide a base document for later content expansion and polishing

Impact

• no product logic changes
• no protocol or runtime behavior changes
• documentation / presentation preparation only

Notes

• this PR is intended as a first-pass outline for the roadshow PPT
• detailed copy, visual assets, and page-level polishing can be added in follow-up updates

Reviewed the added presentation outline across code quality, performance, security, and documentation accuracy. Two documentation issues are worth tightening before others build on this deck; no performance or security concerns in the added content.

The outline for the "core user path" currently compresses the product flow into "user starts -> system judges -> result settles," which drops several parts of the repository’s canonical main chain: task creation/update, local-service orchestration, risk/authorization handling, and formal delivery via delivery_result / artifact / citation. Because this deck is meant to align later content, omitting those stages will push the presentation toward an inaccurate product story.

架构分工ppt appears as a standalone placeholder rather than a numbered section or note, so the deck structure becomes ambiguous here. Readers cannot tell whether this is part of the same presentation, a second deck, or an editing reminder, which makes the outline harder to extend consistently.
