Improvements

Bullets render via overlay: -/*/+ storage stays raw Markdown; the • glyph is drawn, not stored. Copy, save, and .md files are now portable Markdown. Legacy \t• content keeps rendering correctly.
Space-indented nesting ( - foo = 1 level) now matches CommonMark / GitHub behavior.
HTML table paste from browsers (Claude.ai, GitHub) auto-converts to Markdown table syntax.
