Changes:
- **Search**: Replaced Inkeep with Fumadocs' native built-in search
(createFromSource). Removed @inkeep/cxkit-react and custom search
dialogs.
- **Hydration Fix**: Removed markdown links from ### headings in
egress.mdx (across all versions) to fix the <a inside a> DOM mismatch
error.
- **Console Fix**: Added the missing key prop to <VersionSelector/> in
the layout to resolve the React list warning.
