docs(links): update README to reflect current link checkers

The rendered-content-link-checker.ts script and its rendered-content-link-checker-cli
npm command were removed when the link-checking system was rebuilt, but
src/links/README.md still documented them, including obsolete options
(--level, --check-external-links).

Replace them with the current checkers (check-links-pr, check-links-internal,
check-links-external), document their options, add the components/ path to the
LinkPreviewPopover.tsx reference, and update the stale performance note.

 ### Scripts (`src/links/scripts`)
 
-- **`rendered-content-link-checker.ts`**: A comprehensive CLI tool that:
-  - Renders content pages to HTML.
-  - Parses the HTML to find all `<a>` and `<img>` tags.
-  - Validates internal links (checking for 404s, broken anchors).
-  - Validates external links (with caching and retry logic).
-  - Reports flaws and can comment directly on GitHub Pull Requests.
+- **`check-links-pr.ts`**: Fast validation of internal links in the files changed by a pull request. Runs in under 10 minutes on typical PRs and can post flaws directly on the PR.
+- **`check-links-internal.ts`**: Comprehensive check of all internal links across all versions and languages. Designed to run as a scheduled workflow (twice weekly).
+- **`check-links-external.ts`**: Validates external URLs in content files. Designed to run weekly with aggressive caching.
 - **`check-github-github-links.ts`**: Ensures that we don't accidentally link to private `github/github` URLs in public documentation.
 - **`update-internal-links.ts`**: A CLI wrapper around the library function to perform bulk updates on the content files.

 ## Current State & Known Issues
 
-- **Performance**: The `rendered-content-link-checker` is resource-intensive because it renders pages. It uses concurrency limits and caching (especially for external links) to mitigate this.

 - **False Positives**: External link checking can be flaky due to temporary network issues or anti-bot protections on target sites. The system uses a "retry and cache" strategy to reduce noise.
 - **Liquid Complexity**: `update-internal-links` has to use regex and heuristics to parse Markdown mixed with Liquid, which is inherently fragile compared to a full AST parser, but necessary to preserve code formatting.
