Subject: [PATCH] setup.sh runs install steps; Snakefile has working example
 rules

- setup.sh now runs uv sync, copies config template to config.yaml,
  and installs pre-commit hooks after prerequisite checks pass
- Replace commented-out Snakefile placeholder with functional example
  rules (process_data, summarize) that use config.yaml
- Add example workflow scripts (process_data.py, summarize.py) so the
  pipeline is runnable out of the box
