Add isolated Prospect Engine prototype

[DealPatrol]

Summary

• Add a hidden /prospects prototype for RepoFuse Prospect Engine.
• Add token-gated GitHub discovery with mock fallback when GITHUB_TOKEN is unavailable.
• Add explainable lead scoring, sample prospects, detail pages, and human-approved outreach draft review.

Safety notes

• Does not modify the homepage, dashboard nav, middleware, auth flow, billing, or existing database schema.
• Does not send outreach automatically or write prospect data to the database.

Testing

• pnpm exec tsc --noEmit
• pnpm exec eslint app/prospects lib/prospect-engine
• Dev server route smoke checks:
  • GET /prospects -> 200
  • GET /prospects/discover -> 200
  • GET /prospects/discover?run=1&minimumRepos=10&keywords=saas%2Cai%2Cnextjs&language=TypeScript&minimumFollowers=0&limit=3 -> 200 mock mode
  • GET /prospects/mock-maya-chen -> 200
