Document the two `.drone.yml` shapes used across the org, derived from the
repos:
- Type A `python-lib.yaml`: build-and-publish-pypi + backfill-pypi-from-tags
- Type B `service-docker.yaml`: build-and-deploy-service + build-and-deploy-site
- add reference page `10_drone_pipelines`
- vendor `src/templates/drone/` into the MCP bundle (`drone.json`)
- expose `registry://drone` + `list_drone_templates` / `get_drone_template`
- wire `build.py` to vendor drone templates; rebuild nav/index (14 modules)
