docs: the README carries 0.2.0's features and a measured first-load size

Feature bullets grow by chapter numbering, list styles, password
protection, the letter gallery, threaded comments, the book layout and
a Word/LibreOffice interoperability line; the beta note links the open
items. The size claim is measured over the wire (under 2 MB, footnoted),
and a browser bullet says where Save writes back to the file.
