chore: bootstrap repo with PRD, tasks, design samples, and Mosaic scaffolding

Personal professional website for jasonwoltje.com, built on Payload CMS 3 +
Next.js 16 and deployed to w-docker0 (Docker Swarm) behind the existing
MosaicStack edge Traefik. Establishes the delivery contract before any
scaffold work begins:

- docs/PRD.md — stack, content model, routing, design system, CI, infra,
  acceptance criteria, assumptions, and escalation log
- docs/TASKS.md — milestone breakdown 0.0.1 → 0.1.0 MVP
- README.md, LICENSE (All Rights Reserved), .gitignore
- design-samples/ — stitch "Technical Editorial" mockups + DESIGN.md tokens
- images/ — source headshots (to be imported into Payload media on seed)
- .mosaic/ — orchestrator scaffolding (quality rails, repo hooks)

Scaffold (Next.js + Payload init) ships on feat/scaffold in a follow-up PR.
