fix(tests): update exploding_decay signature to match Phase B memories= param

The Phase B consolidation-scoped cache (80ccc2f) added an optional
memories= parameter to run_decay_cycle. The regression test's fake
was pinned to the old 2-arg signature, so CI failed with TypeError
'takes 2 positional arguments but 3 were given'. The fix was already
in the working copy but was not staged into 80ccc2f (only mcp_server/
was added). Committing now to unblock CI on v3.11.0.
