## Summary
- fix hassfest validation by replacing raw options-description URLs with Home Assistant translation placeholders
- extend the pytest CI matrix to cover the latest patch release for each Home Assistant month, plus dev
- align CI/dev container Python versions and tests with newer Home Assistant behavior
## Validation
- GitHub Actions pytest matrix passed for 2024.12.5 through 2026.4.3 plus dev
- Docker passed for linux/amd64 and linux/arm64
- hassfest, HACS validation, pre-commit, pre-commit.ci, markdown-code-runner, docs build, and Release Drafter passed
Add automation to keep the pytest test matrix up-to-date with latest
Home Assistant Core releases:
1. **Weekly Automation**: New workflow updates test matrix automatically
2. **Version Fetcher**: Python script queries GitHub API for latest HA Core releases
3. **PR Creation**: Automatically creates PRs when new versions are available
## Benefits
- No more manual updates when new HA Core versions are released
- Automatic tracking of new HA Core releases
- Reduces maintenance burden
## Background
This builds on commit a982acb which fixed mypy-dev pinning. While upstream
now installs latest mypy-dev automatically, the test matrix versions still
need manual updates. This automation solves that remaining manual task.
