The paste conversion (issue #30) already handled tables, but any
text/html flavor on the clipboard bypassed it. Code editors (VS Code
with copyWithSyntaxHighlighting) ship the plain text a second time as
styled div/span HTML, so a Markdown table copied there arrived verbatim
while the same text from a plain editor converted fine. Clipboard HTML
without a single structural element (table/list/heading/link/emphasis/
code...) is now treated as equivalent to the plain text; anything from a
rich-text source keeps going through ProseMirror's HTML paste.

Pasting inside a code block never converts anymore -- text is code
there, and the conversion would have split the block around rich nodes.

Hand-typed tables: pressing Enter at the end of a GFM separator row
whose previous sibling is a pipe row replaces the two paragraphs with a
real table (input rules cannot express this -- they see only one
textblock). Conversion is refused inside existing tables; body rows are
then typed cell-wise, with Tab appending rows (#338).

Closes #339
