SAAC Daemon 5b37f88477 Harden template for production: add comments, fix bugs, add lock file
- Add inline comments to docker-compose.yml explaining the 5 key rules
  (expose vs ports, DB host, DB name persistence, no Traefik labels)
- Add comments to Dockerfile explaining multi-stage build, layer caching,
  and why .dockerignore excludes client/dist
- Add comments to .dockerignore explaining each exclusion
- Fix dev script: use nodemon (auto-restart) instead of node for server.js
- Add postinstall script to auto-install client deps (cd client && npm install)
- Fix SPA fallback: bare return → next() to prevent hanging requests
- Add root package-lock.json for deterministic server dependency installs
- Remove committed tsconfig.tsbuildinfo build artifact, add *.tsbuildinfo to .gitignore
- Update README: simpler install (npm install handles everything), reference SAAC_DEPLOYMENT.md,
  use npx instead of pnpm dlx for shadcn components

# SAAC Application Stack
# See SAAC_DEPLOYMENT.md for full deployment rules and common mistakes.
#
# Key rules:
# 1. Use "expose", NEVER "ports" — Traefik handles routing
# 2. Database host = service name ("postgres"), NEVER "localhost"
# 3. Do NOT change POSTGRES_DB after first deploy — Docker volume keeps the old name
# 4. Do NOT add Traefik labels — SAAC uses file provider, labels are ignored
# 5. Keep it simple — get this working first, then iterate
