fix(web): start CTAs → /auth/register + GitHub link → claude-intercom OSS

All conversion CTAs were pointing to the dead github.com/claudemesh/
claudemesh repo or # hash fragments. Landing is the primary funnel for
v0.1.0 — every "Start" button is a conversion-critical surface.

Fixes:
- Header "Start free" → /auth/register
- Header GitHub nav item → REMOVED (kept the icon button, repointed)
- Hero "Start free" → /auth/register
- Pricing 6× CTAs: Solo/Pro/Plus/Team/Business → /auth/register,
  Enterprise → /contact
- CTA footer "Star on GitHub" → /auth/register ("Start free")
- BeyondTerminal "Read the protocol spec" → /auth/register
  ("Get on the mesh")

GitHub reinstated as a dedicated icon button in the header right side,
pointing to https://github.com/alezmad/claude-intercom — the MIT OSS
foundation claudemesh is built on. Honest provenance: claude-intercom
is the local peer-mesh gift to the community, claudemesh is the hosted
cross-machine extension.

Tooltip: "Built on claude-intercom · MIT open source".
