fix(web): replace 9 placeholder # links + 2 jargon phrases

Surgical fixes on shipped marketing sections. All changes are link
targets (9) or two-word replacements (2) — no structural edits.

Links:
- "Read the docs" / "documentation" (hero, cta, features) → point
  to the public CLI repo README (canonical docs until /docs exists)
- "Pair your machines" (laptop-to-laptop) → /auth/register
- "Open the dashboard" (surfaces, meets-you) → /dashboard
- "Install" (meets-you) → CLI repo README install section
- "VS Code" / "JetBrains" (meets-you) → CLI repo README (MCP setup)

Copy:
- "self-nominates" → "volunteers"
- "surfaces the history" → "shares the history"

Additive polish per the v0.1.0 web prototyping rule.
