v3.27.0

Added

• analyzeText() can score rendered Markdown instead of source-only
  metadata (#123). Pass sourceMode: "rendered-markdown" to mask initial
  YAML frontmatter and HTML comments before pattern and document analysis.
  Code-span comment examples remain visible, frontmatter recognition accepts
  LF, CRLF, and CR without hiding thematic-break sections, and masks preserve
  issue and sentence-highlight offsets. stats reports the selected mode,
  explicit fallbacks, and masked-span counts. Plain mode remains compatible
  with its existing scoring behavior.
