Subject: [PATCH] test(lbug): de-brittle the close/CHECKPOINT structural guard
 (#2264 review P2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

lbug-checkpoint.test.ts grepped the adapter SOURCE (comments included) for
conn.close()/db.close()/.query('CHECKPOINT') literals, coupling a passing test to
comment wording — a prior commit had to reword a comment just to keep it green.
Strip comments from the read source before the structural assertions so they
reflect code only; the invariant (exactly two CHECKPOINT sites; close calls only
in safeClose) is preserved and no longer breaks on a comment edit.
