fix(scripts): improve nix options doc generator
- Restore missing description on hm enable option (fixes nix build warning)
- Rewrite format_default_value into format_value with example support and nix code blocks
- Fix Nix markup stripping: {tag}`content` now preserves backtick content
- Generalize ::: block handling beyond {.note} to any block type
- Switch output from Markdown table to labeled fields format
