Integration Test InfraFunction

[JEJodesty]

Plan & Test:
Data verified Sub-Process executions are configured and executed by InfraFunction

Status / Context:
tests/verification_test.py exercises the full Processor.Ingress() → Integration() → Egress() path (cats/executor/function/init.py) through InfraFunction on every run

• Integration() dispatches the Process sub-proc via infrafunction_subproc as a real Ray Job on the Plant's cluster and verifies the result lands in the shared MinIO bucket.
• Ingress()/Egress() are exercised in the same run via infraFunction.ingress_subproc/egress_subproc.
  docs/TODO.md's "MinIO-backed distributed Ray Data writes" Done entry documents this same verified data path, including live confirmation that distributed writes land in the shared bucket. Closing.

AC - Plan & Integration Test the following:

• Plan & Test Integration Sub-Process using InfraFunction
• Plan & Test Ingress & Egress Sub-Processes using InfraFunction
