Fixed

• Retry one gold verification only when the first attempt failed before any test
  executed while acquiring dependencies. Both attempt receipts are retained
  across direct, batched, Harbor, and worktree validation; network activity
  during repository tests remains a normal test failure. (f033b557)
• Let CMake/CTest plans ignore non-test support paths in a test patch while
  still requiring exactly one declared test source to select a target.
