Add auto-research Frontstage board

[huangruiteng]

Motivation

Productize the decentralized auto-research path as a public-safe Frontstage board without changing the existing public first screen. The page turns the k-NN auto-research pack into a user-facing surface: research contract, per-agent frontier, evidence graph, promotion/retry/retire candidates, and showcase projection.

Changes

• Add docs/product/auto-research-frontstage-board.public.json as the public-safe board data contract.
• Add /frontstage/auto-research as an experimental dashboard route backed by that contract.
• Extend smoke:frontstage-route to verify the route, value metrics, decentralized topology, evidence graph, decision candidates, no live status dependency, no write form, and public/private boundary markers.

First-screen boundary

This PR does not modify the README, hosted Frontstage homepage, showcase index, existing first viewport, primary CTA, or opening navigation. The new board is an unlinked experimental route for reviewable auto-research productization.

Validation

• python3 examples/decentralized-auto-research-protocol-smoke.py
• python3 examples/decentralized-auto-research-frontier-smoke.py
• python3 examples/auto-research-knn-pack-smoke.py
• npm run smoke:frontstage-route
• npm run build
• git diff --check
• loopx check --scan-path apps/dashboard/src/views/frontstage-auto-research-page.tsx --scan-path apps/dashboard/src/router.tsx --scan-path apps/dashboard/smoke/frontstage-route-smoke.ts --scan-path docs/product/auto-research-frontstage-board.public.json

LoopX check warning observed: existing loopx-meta duplicate index rows warning; touched-file public boundary scan passed.

Findings: none.

Open questions: none; this is an unlinked experimental /frontstage/auto-research route and does not alter the existing public first screen, primary CTA, or opening navigation.
