Update build system (#20)

* Migrate dependency management to uv and configure Lektor build

- Add pyproject.toml with lektor and plugins (lektor-jinja-content,
  lektor-gulp) as uv-managed dependencies
- Remove [packages] section from .lektorproject since plugins are
  now installed via uv into the project venv
- Add .venv/ to .gitignore; commit uv.lock for reproducible installs
- Build with: uv sync && uv run lektor build

* Add GitHub Actions workflow to deploy to Cloudflare Pages on merge to master

Builds the Lektor site with uv and deploys to Cloudflare Pages
using wrangler. Requires these GitHub secrets/variables:
- CLOUDFLARE_API_TOKEN (secret)
- CLOUDFLARE_ACCOUNT_ID (secret)
- CLOUDFLARE_PROJECT_NAME (variable)

* Deploy develop branch to dev preview on Cloudflare Pages

Trigger the workflow on both master and develop branches.
Pass --branch to wrangler so Cloudflare Pages treats master as
production and develop as a preview deployment.
