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.

+# A stuck run is killed and fails; no auto-restart, no Stop button
+
+When a checkpoint passes its time limit, the Run tab kills the bot's whole process tree and ends the run as failed: "Stuck at <checkpoint>, run again". It does not restart. There is no Stop or Pause button. A run also ends early when the operator closes the window, which asks first and then kills the process tree.
+
+**Why:** Tebra Auto Post restarts a stuck bot up to 3 times. That is only safe because its SQL batch table lets a restarted bot skip work it already did. The Run tab skill has no DB (decision Q2), so a restart could do work twice, for example post a payment twice. Tebra removed Stop on purpose ("a run always goes to completion"), and the Run tab keeps the same look.
+
+**Reopen if:** a project's bot is rerun-safe (it skips items already done). Then auto-restart ×3 can come back as an option.
