BlockNote's serializer outputs `*` for bullet lists and inserts ` `
HTML entities around inline code within bold text. Both cause meaningless
git diffs. Fix by post-processing in compactMarkdown:
- Normalize `*` bullet markers to `-` (standard convention)
- Decode HTML entities like ` ` back to literal characters
- Skip normalization inside fenced code blocks

blocksToMarkdownLossy() inserts blank lines between every block, making
tight lists loose and polluting git history. Add compactMarkdown() that
collapses inter-list-item blanks and excessive blank line runs while
preserving code blocks and intentional paragraph spacing.
