[Hugo0]

Summary

• Streamlines README setup instructions

Files changed

File	Change
requirements.txt	Deleted — replaced by pyproject.toml
pyproject.toml	Added project metadata + dependencies
uv.lock	New lockfile for reproducible builds
.github/workflows/test.yml	Uses astral-sh/setup-uv@v5 instead of pip
Dockerfile	Installs uv from official image
render.yaml	Build command uses uv
playwright.config.ts	uv run gunicorn instead of venv/bin/activate
package.json	pnpm dev uses concurrently + uv run gunicorn
