For the code
` _, out = cpn.output(allow_partial=False)`
` def output(self, allow_partial=True) -> Tuple[str, Union[pd.DataFrame,
partial]]:
o = getattr(self._param, self._param.output_var_name)`

### What problem does this PR solve?
Fix#6600
Hello, I have the same business requirement as #6600. My use case is:
We have many departments (> 20 now and increasing), and each department
has its own knowledge base. Because the agent workflow is the same, so I
want to change the knowledge base on the fly, instead of creating agents
for every department.
It now looks like this:

Knowledge bases can be selected from the dropdown, and passed through
the variables in the table. All selected knowledge bases are used for
retrieval.

### What problem does this PR solve?
Fix: Resolved a bug where sibling components in Canvas were not
restricted to fetching data from the upstream when parallel components
were present.
Issue: When parallel components existed in Canvas, sibling components
incorrectly fetched data without being limited to the upstream scope,
causing data retrieval issues.
Solution: Adjusted the data fetching logic to ensure sibling components
only retrieve data from the upstream scope.
