test: skip flaky redaction test in agent-less environments (#289)

This test depends on session state that varies with test ordering.
It passes when run in isolation or with the full hermes agent, but
fails intermittently in the standard test suite. Add to the
auto-skip list alongside other agent-dependent tests.

Fixes #289
