Prepare Vercel-ready project landing page

[Huynhthuongg]

Summary by cubic

Redesigned the FastAPI dashboard into a Vercel-ready landing page and wired serverless deployment with a Python ASGI entrypoint and safe compile output routing. Released 0.1.2 with README badges, CI matrix, and tests.

• New Features

  • Added vercel.json to rewrite all routes to api/index.py and set UPCA_OUTPUT_BASE=/tmp/upca for serverless-safe writes.
  • Introduced api/index.py ASGI entrypoint that exports the app for Vercel.
  • Updated dashboard to a polished landing page served from INDEX_HTML, using public /plan and /compile routes, with links to /docs and GitHub.
  • Enforced safe relative output_dir in both API and CLI; API compiles to UPCA_OUTPUT_BASE / output_dir.
  • Bumped version to 0.1.2 in code and pyproject.toml; added scripts/check.sh; expanded CI to Python 3.10–3.12 and pytest -q.
  • Improved .vercelignore/.gitignore; enhanced README with badges and Vercel deploy steps; added tests validating routing, env usage, and entrypoint.

• Dependencies

  • Added requirements.txt with fastapi, uvicorn, and pydantic.
  • Added dev httpx2 to support the current test client stack.
