feat(skill): add genius-life creativity practice skill (#299)

* feat(skill): add genius-life core skill files

Add genius-life/SKILL.md and the six references/ files (creative-process,
practice-mode, development-mode, practices-catalog, evidence-basis,
scope-and-safety) as original synthesis from the mission research library,
with copyright-compliant paraphrase, named-fellow attribution, and honest
framing. Templates, README, evals, and catalog integration ship in later
features.

* feat(skill): add genius-life templates, README, and evals

Add six fillable worksheets (talent audit, session plan, project
worksheet, conditions audit, incubation log, risk and failure review),
a human-facing README with the repository's required sections, and a
12-case eval manifest covering both modes and the required boundary
behaviors.
