Move all completed items (security hardening, structured logging, dark mode,
export, webhooks, scheduled analysis, multi-model, trend charts, CI, etc.)
into a new Completed section. Reorganize remaining P1/P2/P3 items to reflect
current priorities. Add new next-horizon items: historical diffing, patent
classification tagging, user API keys, batch export, and multi-tenant support.
