Cycle 14: constructor ValueError → ProgrammingError at DBAPI boundary

Per PEP 249, ProgrammingError covers programming-level mistakes at
the API (bad argument types, bad parameter shapes, etc.). timeout=-1
is exactly that. ValueError leaked out of the dbapi's public
connect()/Connection()/AsyncConnection() surface; swap to
ProgrammingError for hierarchy consistency.

Client layer keeps ValueError — it's pre-DBAPI, below the PEP 249
surface, and ValueError is right there.
