# Steps:
#   1. Verify services reachable (ollama, TEI, qdrant)
#   2. [DISABLED] Pull base model (~8 GB) — enable when ready
#   3. [DISABLED] Build vault-tagger modelfile — depends on step 2
#   4. TODO: Install Python deps for lib/
#   5. TODO: Generate initial vocab (lib/vocab_gen.py)
#   6. TODO: Install git pre-commit hook
#   7. TODO: Install cron job from config.yaml schedule
