Drives both EventStore (SQLite reference) and FsEventStore with
identical event streams and asserts query() result sets match. SQLite
throws on blocked inserts (NIP-09 tombstones, NIP-62 vanish, NIP-40
expiration) while the FS store silently skips — both are observable
"event not persisted", so insertBoth() catches SQLite throws and
parity is judged on the post-insert state.
Coverage: id lookup, kind+author, since/until/limit, single-letter
tag query (OR within key), replaceable winner, replaceable older
rejected, addressable d-tag dedup, deletion by id (incl. block-
reinsert), deletion by address (incl. cutoff semantics), expiration
sweep, NIP-50 single-token search (sticking to ASCII where SQLite's
unicode61 tokenizer agrees with our port), count, multi-filter
union, delete by filter, mixed kitchen-sink scenario.
113 fs tests now green (97 unit + 16 parity).
