MechaCat02 7275e156df feat(app): drop the known-words seed, and make a full wipe actually wipe ...

The seed pre-marked the artifact's 30 headwords secure on first run. Two
reasons it is gone rather than merely disabled:

It was never 30 cards. The match was on headword, and homographs each
carry their own lemma, so 그 as pronoun and as determiner both matched —
47 rows for a 30-word list.

Worse, "Reset everything" deleted the cards and then deleted the
'seed.known' guard along with the other meta keys, so the next boot
re-seeded and the deck looked untouched. The one thing a wipe exists for,
undone by the wipe itself.

Migration 5 clears the seed from installs that already have it. seedCard()
is the only writer that leaves updated_at = 0 on a card and the seed was
its only caller, so `DELETE FROM card WHERE updated_at = 0` removes exactly
the seeded rows and nothing the learner graded — the timestamp rule paying
for itself a second time.

test/domain/reset.test.ts pins both scopes: what a full wipe must leave
empty, what a roadmap reset must keep, that the deletions are tombstoned
so a sync cannot restore them, and that migration 5 really runs against a
schema-4 database rather than the test performing the delete itself.
