fix: search suggestions not loading on first open

[rsbh]

Summary

• Replace useDocsSearch from fumadocs with custom fetch + lodash debounce
• Fumadocs hook's useOnChange skips initial render callback, so suggestions never load until user types and clears
• Now fetches suggestions immediately when search dialog opens
• Abort controller cancels in-flight requests on new search

Test plan

• Open search dialog (Cmd/Ctrl+K) — suggestions should appear immediately
• Type a query — results should load after 150ms debounce
• Clear search — suggestions should reappear
• Close and reopen dialog — suggestions load again
• Test with versioned docs — tag param passed correctly
