docs: add sunset notice for May 15 shutdown of Roo Code products

[roomote-v0]

Opened by @roomote-v0 on behalf of Raphi Winkler

Add prominent sunset notice across the docs site informing users that all Roo Code products (Extension, Cloud, and Router) will be shut down on May 15, 2025.

Changes

• AnnouncementBanner: Updated from PR Reviewer promo to a non-dismissible red sunset warning banner visible on every page, linking to the new /sunset page
• docs/sunset.md: New dedicated page with full sunset details including timeline, what happens on May 15, billing contact info, and recommended alternatives (Cline, roomote.dev)
• docs/index.mdx: Added a prominent danger admonition at the top of the home page with key sunset info and links

These changes ensure the Intercom support bot (which references docs content) will surface sunset information when users ask about Roo Code products.

• Sunset date "May 15, 2025" is in the past (current date is April 2026) -- all copy uses future tense for an event that already occurred. Update the year or rewrite in past tense.
• docs/sunset.md has sidebar_position: 0 frontmatter but is not listed in sidebars.ts, so it won't appear in the sidebar. Either add it to sidebars.ts or remove the misleading frontmatter.

The sunset date "May 15, 2025" is nearly a year in the past (current date is April 2026). The banner, index admonition, and this page all use future tense ("will be shut down") for an event that already happened. Either the year should be 2026, or the copy needs to be rewritten in past tense to reflect that the shutdown already occurred.

The sidebar_label and sidebar_position: 0 frontmatter suggest this page should appear in the sidebar, but sidebars.ts is manually configured and doesn't include "sunset". The page is only reachable via the banner and index admonition links. If sidebar visibility is intended, add "sunset" to the items array in sidebars.ts. If not, consider removing the sidebar_position frontmatter to avoid confusion.
