chore: bootstrap project structure (.tasks, .wiki, CLAUDE.md)

Adds canonical Karpathy LLM Wiki layout, .tasks/STATUS.md board,
and CLAUDE.md trigger set. Brings factory repo into projects-meta
indexing eligibility (sync-runner.ts:69 — needs .tasks/STATUS.md or
.wiki/index.md on default branch).

Bootstrap-manifest at .wiki/concepts/bootstrap-manifest.md records
skill versions used (project-bootstrap@1.7.0, layouts inline-fallback
from setup-wiki@1.0.0 / setup-tasks@1.0.0).
