Renumber to 0116: another record took 0115 on main

PR #133 landed a different 0115 while this branch was open. The bus record
is now 0116, with every citation in designs 19, 25, 28 and the index
following it.

Note: cycle.py and records.py both fail on main as merged, on that record —
nothing cites it, and it rests on 0112, which is still proposed. Both
pre-date this branch and are left for their own change.
