Analyze Memory Consumption and Performance Optimization

[hendriknielaender]

I've noticed potential areas in zvm where we might be able to improve memory consumption and performance, specifically related to allocators, pointers, and buffer sizes. To ensure we are utilizing resources in the most optimal way, I propose a thorough analysis and benchmarking before and after the optimization.

Goals:

1. Memory Consumption: Understand where our application is using the most memory. Check if we can reduce the memory footprint in those areas without affecting performance or functionality.
2. Allocator Analysis: Check if we are using the right kind of allocator for different tasks. For example, std.heap.page_allocator might be suitable for large allocations, but for small and frequent allocations, we might benefit from using something like std.heap.ArenaAllocator.
3. Pointer & Buffer Size Optimization: Ensure that we aren't over-allocating memory for pointers and buffers. This can be a subtle source of inefficiency.
4. Performance Benchmarking: We need to benchmark the current CLI's performance. After any optimizations, re-run the benchmarks to compare and document any improvements.

Expected Outcomes:

1. A detailed report on current memory usage patterns and areas of potential optimization.
2. Updated CLI code with implemented optimizations.
3. Before-and-after benchmark results, showcasing the improvements (if any) from the changes made.
