Release notes

Fixed

• MD013: CRLF line endings are now preserved during semantic-line-breaks reflow, fixing false positive warnings in the LSP when editors send Windows-style line endings (#459)
• MD041: Fix mode now correctly passes the file path to LintContext, enabling filename-derived title insertion (InsertDerived). Index and README files now derive their title from the parent directory name instead of “Index” or “README”
• MD044: YAML frontmatter values are now checked as prose while keys, delimiters, comments, and flow constructs are skipped. TOML frontmatter keys are also correctly skipped (#448)
• MD044: Angle-bracket autolinks (<https://...>) inside HTML comments are no longer flagged for proper name violations. Uses CommonMark autolink pattern matching for all valid URI schemes (#457)
• MD076: Blank lines required by MD031 (blanks-around-fences) and MD058 (blanks-around-tables) inside list items are now recognized as structural rather than inter-item separators, preventing false positives in tight lists with code blocks, tables, or HTML blocks (#455)

Changed

• Removed unused itertools dependency
