This commit addresses severe UI freezes and garbage collection thrashing (JS_CallInternal) caused by processing thousands of streaming grep matches. Key optimizations: - Throttled Streaming: Cap UI rebuilds during active searches to run at most 10 times per second (100ms interval) instead of on every chunk received. - Array Allocation: Replace O(N^2) `Array.concat()` with an in-place `push()` loop to avoid massive memory allocations when merging match results. - Strict UI Virtualization: Modify `buildPanelEntries` to map a flat list of items and strictly compute display strings, padding, and regex highlights ONLY for the rows currently visible in the viewport.
