test(ooxml): Sprint 10 - Error variants + conversion edge cases
Error module tests (10 new): - Error message formatting for all variants - IO error conversion (From impl) - JSON error conversion - Result type alias usage - Debug format verification - Distinct error message validation Conversion edge case tests (10 new): - All formatting combinations (bold+italic+monospace) - Hyperlink with anchor only - Hyperlink with neither id nor anchor - Hyperlink with missing relationship - Paragraph with mixed children types - Empty run text handling - Unicode anchor generation - Long text anchor generation - Empty document conversion - Table with empty cells 286 tests total (up from 266) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
