fix: strip blockquote continuation prefix from table rows in parser

get_node_text() only applies col_start offset to the first line of a
tree-sitter node. For tables inside blockquotes, lines 2+ retain the
'> ' prefix, causing the lpeg row parser to fail silently and produce
empty results. This left separator and data rows unrendered.

Strip the prefix via line:sub(col_start + 1) for lines after the first,
and skip empty/blank lines (e.g. trailing '>' markers).
