Add research playbook for EWRL pilot runs and paper submission

A self-contained walkthrough covering: merging PR #26, pre-pilot prep
(W&B login, alerts config, smoke test, compute decision), running the
9 pilots (commands, monitoring, when to kill early), analyzing results
(compare.py + analyze.py), drafting the EWRL paper, and parallel
research-ops tasks (Oracle IP, NCSA grant, NC State advisor).

Includes a timeline arithmetic section showing ~14 days of slack
against the 2026-05-25 EWRL deadline if pilots take 10 days, and a
quick-reference command cheat sheet at the end.
