fix(linkedin-snippets): search-results accumulator survives full page loads

The snippet's accumulator was a bare window global, written when
LinkedIn's Next pagination was a soft SPA navigation. Pagination now does
a FULL page load (observed on the operator's capture run 2026-07-27),
wiping window every page — so each run restarted the table at zero
instead of appending.

The accumulator now writes through to localStorage after every run and
restores from it on paste, so page 2 reports "restored N rows" and keeps
counting. __liClear() clears both memory and the stored copy. Usage flow
unchanged: paste per page, __liDownloadCsv() when done.
