Tier: low

• Homepage only: the hero install command becomes a Windows / Linux, macOS, Termux / Python (uv) selector.
• The docs workflow now builds the site on pull requests; deploy still runs only from main.
• No change to the CLI, the install scripts, README or other docs pages.

Changes

• Replace the single Python-only homepage command with tabs for Windows, Linux/macOS/Termux, and Python (uv).
• Match the documented recommended native installation path while keeping the Python option.
• Update both English and Korean homepages and link to the complete installation guide.
• Preserve the existing homepage layout, VitePress theme, and copy interaction.
• Resolve the installation-guide link under the /codigest/ base path (it pointed at a 404 on Pages).
• Select the visitor's platform after hydration, use $ for the POSIX prompts, announce the copy result to screen readers.
• Wrap Korean on the homepage between words instead of between syllables.
• Build the site on pull requests in docs.yml without configuring or deploying Pages.

Validation

• cd site && npm ci && npm run build passes locally (VitePress 1.6.4, Node 24).
• Headless Chromium render of en/ko home and installation at desktop and mobile widths, dark and light: no console errors, no failed requests, no horizontal overflow; keyboard selection and copy work. Results and screenshots in the comment below.
• Internal link check over the whole build: one remaining broken anchor, which is on main already and handled separately.
• Not checked: real screen readers, Safari/Firefox, the deployed Pages site.
