fillna() can be implemented as a post-processing task.
dropna() can be implemented as a query filter
For now we can support axis only as axis=1 for "columns", some options may be supportable but others may be tougher.

Research direction
Start by locating the existing DataFrame and Series implementations and their query-filter and post-processing paths. Define the supported behavior for fillna() and dropna(), including axis=1 for columns, then verify that both APIs handle the agreed options and preserve expected DataFrame or Series results.
