fix(portals): depth-track div extraction so nested job descriptions aren't truncated (#204)

The jobindex and linkedin detail parsers matched description containers with a non-greedy regex that stops at the first inner </div>, so any posting whose description contains nested divs was silently truncated (jobindex dropped later sections; linkedin dropped everything after the first block). Replaces the regex with a depth-tracked extractDivContent scanner that walks div open/close markers to the matching close. Verified: truncation bug reproduced against real markup fixtures, depth arithmetic correct (no off-by-one/infinite-loop), 28 tests pass network-free, no regression on non-nested divs. Malformed-HTML over-grabs rather than truncates - the safer failure, cleaned by downstream stripTags/decode.
