generate-site-data.py

Compliance-first site data generator. Reads project-config.json,
enriches with live stats, applies compliance filtering, and writes
sanitized projects.json + stats.json for the portfolio website.

Trust model:
  project-config.json  ->  compliance filter  ->  projects.json + stats.json
  GitHub API (public)  -/

Only visible projects contribute to stats. Private repo commit messages
are stripped. See docs/website_truth_system.md for full architecture.
