v1.0.3

What's Changed

Bug Fixes

• Fix HTML renderer anchor links to use GitHub-style heading IDs — #ref links now resolve correctly
• Fix mypy type-ignore errors across pptx renderer, title promotion transform, and archive parser
• Fix Sphinx documentation build warning from malformed .. deprecated:: directive
• Fix flaky test_detect_latin1 (chardet Latin-1 detection unreliable across platforms)

Improvements

• Upgrade to Black 26.x and pin version to prevent CI/local formatting drift
• Fix pre-commit hook compatibility on Windows (use uv run for subprocess resolution)

New

• Add prebuilt agent skill files (all2md-convert, all2md-view-diff, all2md-search) following the Agent Skills specification — installable into Claude Code, Cursor, VS Code Copilot, Gemini CLI, and other skills-compatible agents
