fix(website): show openspec init in the homepage getting-started box

[clay-good]

Status: Ready. Surgical, website-copy only — no CLI behavior, tests, or generated assets touched.

What was wrong: The homepage's final call-to-action ("Ship your first change in five minutes") shows a single command box containing only npm install -g @fission-ai/openspec@latest. As #1282 reports, that command installs the CLI but "does nothing by itself" — a new user who copies it gets no scaffolding and nothing to run. The README already documents the real flow (install → cd your-project → openspec init); the landing page didn't.

How it was fixed: Added the second step to the box so it reads:

$ npm install -g @fission-ai/openspec@latest
$ cd your-project && openspec init

The box becomes a stacked two-line block (flex-col, left-aligned) and keeps the exact same card styling. No other content changed.

Proof: npx tsc --noEmit in website/ passes clean. Change is confined to the FinalCta component in website/app/(home)/page.tsx; built output under website/out/ is gitignored and untouched.

Notes: Matches the canonical README wording verbatim. No design/architecture change, no golden-hash or template impact.

Closes #1282

Exact head d60babb fixes the incomplete homepage onboarding CTA by adding the canonical cd your-project && openspec init step directly after installation. The one-file diff is clean, the website installs and builds successfully from a clean checkout, and the full hosted cross-platform, security, CodeRabbit, and Cloudflare preview matrix passes. Approved technically; a real second-human approval is still required before merge.
