Renn FandRenzo F 1f769f6315 [sandbox-ext] fix: drop dynamic verify SQL (bandit B608) — static query + Python membership
CI bandit -ll flagged B608 at sandbox.py:264 (f-string ANY(ARRAY[...])
with interpolated feature names). Root-cause fix: verify_step now runs a
static 'SELECT extname FROM pg_extension' and verify_ok checks set
membership against the installed extnames — no interpolation, no string-
built-SQL surface, and a more correct check (membership vs count). The
enable_step CREATE EXTENSION stays (identifiers can't be parameterized;
allowlist-validated upstream, the containment). Tests updated from the
count-based exec_out to the extname-list exec_out.
