Automate the evaluation on a weekly schedule

- scripts/sync-catalog.mjs: rebuilds the Go catalogue from models.dev and benchmark
  scores from Artificial Analysis, and records what changed in snapshot.json
- scripts/build-models-md.mjs: regenerates MODELS.md from the data layers
- scripts/notify-new-models.mjs: files an issue when a new model needs a write-up
- weekly-eval.yml: cron every Monday 05:23 UTC -> refresh -> commit -> Pages deploy
- site now renders every model in the catalogue (33) with a data-snapshot stamp;
  auto-added models are flagged 'no write-up' until described
- replaced scripts/refresh-evals.mjs with the wider sync script
