fix(remediation): pass LINK_EXTRACTOR_VERSION_TS to the extraction-lag gate

countExtractionLag omitted versionTs, so its predicate diverged from the
counter it claims to share with doctor's links_extraction_lag check and
the extract --stale walk: pages stamped before an extractor version bump
(links_extracted_at < LINK_EXTRACTOR_VERSION_TS) lagged for doctor and
extract but never tripped the sync.repo/extract.all gate. Pass the stamp;
pin the version-bump arm with a backdated-page test (fails without it).
