feat(wasteland): debounce wanted board search input

[jrf0110]

Summary

• Syncs the fork PR that debounces wanted board search input updates before writing q to the URL.
• Keeps local search input responsive while avoiding high-frequency router updates during typing.
• Clears the URL search parameter immediately when the input is emptied.

Verification

• Manually verified in fork PR: search inputs and clear state behavior under latency.

Reviewer Notes

• Source fork PR: feat(wasteland): debounce search input on wanted board to prevent jank jrf0110/cloud#1
• scripts/typecheck-all.sh --changes-only skipped because no matching workspace packages were detected for the changed file.
• pnpm format could not complete due to a pnpm EEXIST symlink collision in node_modules; the worktree remained clean.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

Debounce implementation is correct and clean — the useRef timeout is properly cleaned up on unmount, preventing memory leaks, and the sync-from-URL useEffect correctly handles external navigation changes.

Note: One minor UX observation (not a bug): updateFilterParams trims the search value before writing to the URL (line 182), but localSearch stores the raw input. If a user types trailing spaces, after the debounced URL update fires and the useEffect syncs back search → localSearch, those trailing spaces are stripped mid-typing. This is a very edge case and unlikely to affect real users, but worth being aware of.
