ci: add Makefile for dev setup with prek hooks

[liudger]

Add a Makefile with common development commands:

• make setup — Install dev dependencies and prek git hooks
• make lint — Run all pre-commit hooks via prek
• make test — Run tests
• make coverage — Run tests with coverage report

This ensures prek hooks are automatically installed when setting up the dev environment, preventing lint errors from being pushed without local checks.

Pull request overview

This PR adds a developer Makefile, but it also changes the library’s heating-circuit support and parameter mappings (not reflected in the PR title/description).

Changes:

• Add a Makefile with setup, lint, test, and coverage targets using uv + prek.
• Reduce supported heating circuits from 3 to 2 (remove HC3 sections/params and related tests).
• Update heating circuit 2 parameter IDs (and adjust fixtures/tests accordingly).
