fix: search suggestions not loading on first open

Replace fumadocs useDocsSearch hook with custom fetch + lodash debounce.
The fumadocs hook's useOnChange skips the initial render callback, so
suggestions never load until user types and clears. Now fetches
suggestions immediately when dialog opens.
