What's Changed

Added a Makefile as the entry point for all development tasks (make help lists every target): setup, code quality (ruff, mypy, pylint, bandit, codespell, yamllint, prettier, translations, prek), tests (incl. coverage, CI mode and the opt-in e2e suite), hassfest/HACS validation, running Home Assistant against ./config, and housekeeping. Targets run through script/run-in-env.sh, so they work with or without an activated virtual environment. CLAUDE.md and CONTRIBUTING.md document the targets; the broken cov.sh (it referenced a non-existent .coveragerc) is superseded by make test-cov-html and was removed

Groundwork bump for the still-disabled openccu-loom backend; it has no runtime effect while the backend master switch (LOOM_BACKEND_SELECTABLE in const.py) stays off. Advances the bundled loom client from 2026.7.6 to 2026.7.10 and its transitively pinned openccu-loom-types from 0.1.53 to 0.1.55

Bundled homematic-config.js rebuilt. The device list now renders virtualized (new hm-device-row element behind ha-list-virtualized) once more than 100 filtered devices are shown and Home Assistant provides the element, which keeps large installations responsive; below that threshold the existing grouped rendering is unchanged
The unsaved-changes warning in the channel and link configuration now also triggers when navigating away or closing the tab (capture-phase click interception plus beforeunload), not only via the panel's own back button
