* openspec: propose migrate-ci-to-phcc (proposal + design)
Design-first per repo convention. Migrates pytest + Docker CI off the dead HA core-checkout harness to the PHCC-based local test suite that already passes locally (164). Implementation (tasks + code) held pending review of the design's open questions.
* ci: migrate pytest + Docker off HA core-checkout to PHCC
Implements openspec change migrate-ci-to-phcc.
- pytest.yaml: run the local PHCC suite (latest + dev matrix; dev is
continue-on-error). Fixes the trigger (was push:[master] -> never ran on
main; now main). Drops coverage (was computed but never uploaded). Recipe
verified in a clean env locally: 164 passed, Python 3.13, latest PHCC.
- Delete dead core-checkout scaffolding: install_dependencies action,
setup-dependencies, setup-symlinks, update-test-matrix.{py,yaml},
test_dependencies.py, Dockerfile, docker-build.yml.
- setup-devcontainer: PHCC flow (uv sync --group test).
- tests/README.md: rewritten for 'uv run pytest'.
- CLAUDE.md: drop the 'Refresh test matrix' row.
- hacs.json 2024.12.0 -> 2026.1.0; README min-version line corrected (it
wrongly claimed '2025.1.0 pinned in manifest.json' - manifest pins none).
* openspec: mark migrate-ci-to-phcc 4.3 done (CI verified green)
