Initial commit: BlueCap Strategies Astro site

Static Astro 5 site for BlueCap Strategies with exact live-site content
parity, deployed to k3s via GitOps (ArgoCD).

- Page copy in Markdown content collections (services, focus-areas, pages,
  insights) with a Zod SEO schema enforced at build time
- Homepage + About restored to exact live copy; real live-site imagery
- Build-time SEO linter (scripts/seo-lint.mjs) and Playwright e2e suite
- Multi-stage Dockerfile (nginx serves dist/) and Kustomize manifests (k8s/)
- Per-agent robots.txt; config-driven PostHog + Umami analytics scaffold
- ADRs and engineering docs under docs/
