Add rpa-run-tab skill: Tebra-style Run tab in 5 minutes

The Run tab from Tebra Auto Post, scrubbed and themable (Tebra Sky, TVL Teal,
or a custom hex checked for contrast). The skill wires the real bot through
tagged log-file lines and checks itself with a fake bot (complete, partial,
stuck, crash) plus light and dark screenshots. Grill decisions R1-R14 are in
PLAN.md, terms in GLOSSARY.md, and ADRs 0001-0003.
