[Feat/UI]: Implement Non-Blocking Shimmer Highlighting Layer for Command Palette Row Selections

Problem

When stepping through command palette option entries array paths utilizing shortcut arrows keys, the active row swap triggers instantaneous flat background modifications. This lacks modern interface fluid visual dimensions and fails to provide sharp indicators to operators coordinating high-speed systems failures triages.

Proposed Solution

Develop and assemble an isolated, hardware-accelerated Shimmer Highlighting Layer inside /dashboard/components/palette/ShimmerRow.tsx using Next.js structures and custom Tailwind parameters.

• Apply a dynamic sliding micro-reflection effect (linear-gradient animation tracking vectors) that sweeps across active item selections container boxes seamlessly.
• Enforce layout properties transformations using standard translation shifts (translate-x parameters matching 2px vector indices) to create a smooth interactive lift layout whenever a node is highlighted.
• Keep execution bounded tightly to GPU thread processing paths to maintain zero CPU instruction allocations cycle stalls.

Alternatives

• Static flat color adjustments routines which drops interface attraction multiples across developer directories scanners.

Use Case

Delivers immediate, high-fidelity visual context alignment during high-frequency worker pool lookups, maintaining clean engineering authority.

Additional Notes

Keep style coordinates bound tightly to flat pure-black canvas frames (bg-black / slate-950). Marked under good-first-issue. Drop a comment to get assigned!

Start by reading /dashboard/components/palette/ShimmerRow.tsx and tracing how command-palette row selections are highlighted. Implement the isolated shimmer layer with the specified sliding reflection and 2px translation behavior, while preserving the black/slate styling; done means active rows visibly transition without blocking interaction.
