Agent prompt examples added; coverage rail links fixed

Added

• "What agents ask" section on the homepage — three example prompts showing what the platform answers for agents tracking their stack, ecosystem integrations, and industry trends.

Changed

• Homepage refreshes: the org table now has a "Featured" heading; the hero release count displays in compact form (35.6k-style); signed-out visitors see a signup link under the CLI demo.
• Status removed from the top navigation — it remains accessible via the Admin dropdown.

Fixed

• Coverage siblings in the "N other posts cover this launch" rail no longer link to suppressed pages that return 404 — they render as plain, non-linked rows.
