refactor(runner): drop hardcoded per-app selectors from step log (#10)

interestingTags hardcoded selectors from a specific app (etMobileNumber,
customer_row_, supplier_row_, etc.) inside the generic runner. None of
these selectors exist in the checked-in sample spec. Debug log now just
reports screen + hierarchy size; specs that want richer visibility can
log from state.ax.find themselves.
