fix(porch-store): saturation teardown no longer counts as a check

- Add a neutral note() helper (prints, touches neither pass nor fail)
- Use it for the saturation leg's unconditional teardown line, which
  previously called ok() regardless of branch taken and inflated the
  reported count with a line that could never fail
- New count: 78 checks, 0 failures (was 79) -- every number now is a
  real assertion
