Review Comment:
   🤖 The Javadoc now explicitly states implementations must NOT mutate the 
input `hoodieConfig`. But this test `DisableDictionaryInjector` still calls 
`hoodieConfig.setValue(...)` directly on the input. Since tests often serve as 
reference implementations for users, could you update the test injectors to 
create a copy of the config before modifying it, to match the documented 
contract?
