0.4.0

Added

• numd parse-md — new command that parses markdown into a table of semantic blocks (headers, paragraphs, code blocks, lists, blockquotes, frontmatter) with extracted content and metadata
• Frontmatter parsing support in parse-md (YAML between --- delimiters)
• live.nu module for programmatic markdown building (internal)

Fixed

• Guard against missing closing frontmatter delimiter in parse-frontmatter
• Consecutive same-level headers now correctly split into distinct blocks
• Replace deprecated $nu.temp-path with $nu.temp-dir

Removed

• Unused nu-utils/mod.nu
