slugify, parse_readme, count_entries, extract_preview, render_content_html,
and related helpers are moved to a dedicated readme_parser module.
build.py now imports from readme_parser rather than defining these inline.
Tests for the removed functions are dropped from test_build.py since they
now live with the module they test.

Replaces MkDocs with a bespoke Python site generator using Jinja2 templates
and Markdown. Adds uv for dependency management, GitHub Actions workflow for
deployment, and Makefile targets for local development (fetch_stars, build,
preview, deploy).
