Add bisection probes for testReconstructTable hang source

Isolate which test class before Translation_Tests leaves Turso in a
state that makes testReconstructTable hang in the main run. Probes
run three combinations: Driver_Tests, Metadata_Tests, PDO_API_Tests —
each paired with Translation_Tests and testReconstructTable.

Whichever probe hangs identifies the polluting suite.
