  • Single-Sink-Reset-Base: Repeatedly enable an active source and a single sink, reset CoreSight, and verify the sink consistently disables under load.

  • Single-Sink-Reset-Connected-Base: Stress test sink reset behavior with an actively connected STM source and verify recovery via successful trace read.

Dependency PR: This PR depends on PR #389 and should be merged after it.

This PR depends on #389, so I suggest keeping it blocked until the common CoreSight helper API is finalized.

After #389 lands, please rebase this PR and reuse the shared helper for source/sink setup, single-sink reset, trace readback, cleanup, and result reporting.

The single-sink reset coverage is useful, but it should share the same discovery and cleanup path as the rest of the CoreSight tests.
