[squad:plan] Lattice Hollow — Security & Data Privacy Review: "Quiet Vault" (Kujan)

[github-actions]

Owner: Kujan — Security Engineer

Part of the Lattice Hollow plan (#58481).

Goals:

• Review the demo's data handling and shipping posture, even for a low-risk single-player game.
• Deliverables: inventory of stored data, save-file review, third-party dependency check, telemetry decision record.
• Guidance on minimizing local data collection and avoiding unnecessary network behavior.
• Risk review for crash logs, user identifiers, and build distribution artifacts.

Depends on #58479 packaging approach.
