Vibe Coding — Tech Stack Generator

Generate TECH_STACK.md. Every library gets a version, every service gets a cost estimate.

Prerequisites Check

1. Read progress.txt — technology choices from Topic 6 + run_target
2. Read ./docs/PRD.md — features that drive technology requirements
3. Detect stack type → read only the relevant deployment section:

run_target = local      → READ: ## Deployment: Local
run_target = vercel     → READ: ## Deployment: Vercel
run_target = netlify    → READ: ## Deployment: Netlify
run_target = digitalocean → READ: ## Deployment: DigitalOcean
run_target = desktop    → READ: ## Deployment: Desktop
run_target = other_cloud → READ: ## Deployment: Other Cloud
