Fix dlclive mock structure in processor tests

Update the base processor test helper to better mirror the real dlclive package layout by mocking both `dlclive` and `dlclive.processor`, and add a no-op `process` method on the dummy `Processor`. This prevents import/behavior mismatches in tests that rely on the processor interface.
