Revert temp_store=MEMORY patch — it also crashes testReconstructTable

Even scoping `PRAGMA temp_store = MEMORY` to only the two failing
temp-table test methods (so the patched PRAGMA runs in *those tests'*
PDO connections) caused testReconstructTable to dump core ~5s after
it started in a subsequent test class. The temp_store change must
mutate process-global Turso state that testReconstructTable's pager
later depends on (memory: project_turso_testreconstructtable_fragile).

Drop the patch and leave the two temp-table tests as failing. Update
the workflow comment so future attempts know not to retry this lever.

Net: still at 589/596 with the same 3 failures.
