feat: add productization plan and web UI scaffold

[abrichr]

Summary

• Add comprehensive productization plan at docs/PRODUCTIZATION.md covering market context ($4.7B AI code assistant market), competitive analysis, hybrid pricing model (Free/Pro/Team tiers), 6-week MVP roadmap, go-to-market strategy, technical architecture evolution, and unit economics
• Create Next.js web app scaffold at apps/web/ with landing page, task submission form, and job detail page -- the first step toward a web-based entry point alongside the existing Telegram bot
• Update monorepo config (turbo.json, .gitignore) for Next.js support

Details

Productization Plan

• Pricing: Free ($0, 3 tasks/mo, public repos), Pro ($29/mo, 20 tasks), Team ($99/mo, 100 tasks)
• MVP Roadmap: Week 1-2 GitHub App, Week 2-3 Web UI, Week 3-4 Stripe billing, Week 4-5 multi-tenant queue, Week 5-6 sandboxing
• Unit economics: $0.50-5.10 COGS per task, selling at $5-15, 50-90% gross margin
• GTM: Target small dev teams (2-10 engineers), wedge with bug fixes and dependency updates

Web UI Scaffold (apps/web/)

• Landing page (/) with features, pipeline diagram, language support table, pricing tiers, and open-source CTA
• Task submission (/new) with repo URL, task description, branch, advanced options (max loops, budget cap)
• Job detail (/jobs/[id]) placeholder for real-time status via Supabase Realtime
• Server actions for secure Supabase job insertion (service role key stays server-side)
• Supabase client helpers for both server and browser contexts
• Tailwind CSS with custom wright color palette

Test plan

• Review docs/PRODUCTIZATION.md for completeness and accuracy
• Verify apps/web/ builds: pnpm install && pnpm --filter @wright/web build
• Verify landing page renders correctly: pnpm --filter @wright/web dev
• Verify task submission form validation (empty fields, non-GitHub URLs)
• Confirm turbo and pnpm workspace configs properly include the new app
• CI passes (lint, test, build across all packages)

Review

The productization doc and Next.js scaffold look good overall. However, CI is failing because pnpm-lock.yaml was not updated after adding apps/web/package.json:

ERR_PNPM_OUTDATED_LOCKFILE  Cannot install with "frozen-lockfile" because pnpm-lock.yaml is not up to date with <ROOT>/apps/web/package.json

To fix: run pnpm install locally on this branch, then commit the updated pnpm-lock.yaml.

Not merging until CI passes.
