feat(marketing): CTA pulse animation + breadcrumb repositioned below hero

Homepage:
- Wrap "Continue with Google" in a relative group; add rose-300 pulse
  ring (animate-cta-pulse) that fades out smoothly on hover
- @keyframes cta-pulse added to globals.css (2.6s, scale 1→1.22, opacity 0.45→0)

Blog listing (/blog):
- Remove breadcrumb from above the hero header
- Place it in a pt-5 strip directly above the 3-column content grid
  so it reads as "you are here" navigation rather than floating chrome

Blog post (/blog/[slug]):
- Remove breadcrumb from inside the hero gradient section
- Place it in the same pt-5 strip between hero and 3-col grid for
  consistent placement across listing + post pages
