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.

+## Documentation
+
+- [`docs/PRD.md`](docs/PRD.md) — product requirements, scope, architecture decisions
+- [`docs/TASKS.md`](docs/TASKS.md) — milestone + task tracking
+- [`design-samples/stitch_jasonwoltje.com/silicon_ethos/DESIGN.md`](design-samples/stitch_jasonwoltje.com/silicon_ethos/DESIGN.md) — design system reference
+
+## Deployment
+
+Container images are built by Woodpecker and pushed to `git.mosaicstack.dev/jason.woltje/professional-website:sha-<short>`. The Portainer stack references immutable tags — `latest` is never used as a deploy reference.
+
+See `docs/PRD.md` §Infrastructure for the full deploy runbook.
