remove public docs surface

[nahiyankhan]

Category: improvement
User Impact: The public site now presents only ghost's thesis instead of implying that the project is ready for documentation-led adoption.
Problem: The docs surface and persistent menu suggested an onboarding and support posture that ghost is not ready to maintain.
Solution: Remove the public docs routes, MDX pipeline, menu, generated CLI reference, and related maintenance checks. Keep the homepage as the sole public surface, redirect old paths home, and direct command questions to CLI help.

Validation:

• pnpm check: passed
• pnpm test: 192 passed, 1 skipped
• pnpm build: passed
• Browser check: homepage rendered without a menu; /docs redirected to /

Changeset: added a patch changeset for the public README and documentation-link cleanup.

ghost Review:

• ghost check --base origin/main: not run because the current CLI does not expose a check command.
• ghost review --base origin/main --include-memory: not run because the current CLI does not support --include-memory; visual output was reviewed directly in-browser.
