Release notes

Fixed

• MD053: Resolve false positive for reference links used inside multi-line footnote bodies (#540)
  • Root cause: ENABLE_OLD_FOOTNOTES parser option caused footnote continuation lines to be misidentified as indented code blocks, hiding reference usages from MD053
  • Switched to ENABLE_FOOTNOTES and unified all pulldown-cmark parser option sets across the codebase
  • Added in_footnote_definition field to LineInfo for proper footnote body detection
• MD005, MD007, MD030, MD032, MD046: Skip footnote definition body content to prevent false positives on list indentation, spacing, and code block style within footnotes
• MD045: Recognize Obsidian wikilink image alt text (![[image|alt text]]) as valid
• Output: Suppress summary text in machine-readable output formats (JSON, SARIF, etc.)
