/** /**
* Turbo-charged in-place array filtering. This function mutates the array. * Filter out items from an array in place. This function mutates the array.
* Optimized for both small and large arrays using different strategies: * `predicate` get through the array from the end to the start for performance.
* - For small arrays (<=16 items): Uses splice for better memory efficiency
* - For large arrays: Uses optimized swap-and-truncate strategy
* *
* Processes array from end to start for maximum performance. * This function should be faster than `Array.prototype.filter` on large arrays.
* Benchmarks show this is significantly faster than Array.prototype.filter
* and standard filterInPlace implementations.
