* perf(sqlite): refresh the legacy profile copy hourly and recover crashed row caches - The legacy whole-document refresh rewrote every changed split domain each 5 minutes (~4-8 MB per cycle, ~200 MB/hour of WAL plus checkpoint on an active profile). Writer start and graceful close already bring it current, so refresh at most hourly in between. - Cap the profile-state WAL at 8 MB; without journal_size_limit it stayed at the size of the largest transaction ever written. - Row caches: a read-only startup read cannot roll back a hot journal (or recover a WAL without -shm), so retry once on a writable connection instead of disabling the store on every launch. - Row caches: drop the saved baseline when a commit throws, since COMMIT may report an error after the rows landed and our own commit does not move data_version. * test(sqlite): accept Windows exit status for the crashed-writer fixture; document recovery cost * docs(sqlite): state the crash-recovery cost without overstating its bound * fix(sqlite): rebuild a row cache a crash left needing recovery instead of replaying it on main * revert(sqlite): keep crash-recovery failures non-destructive; drop the rebuild fallback
