OptionalincludeRows-only filter, defaulting to !isRegenerable. DDL is always emitted, so a trimmed dump

Optionallimitrows per table, for a cheap sample; 0 or absent is every row
Optionalmaxcharacters per chunk for dumpChunk; see DUMP_CHARS_PER_CHUNK

options that shape a dump; a resumed export must repeat them
