No changes needed - memory management implementation is correct

[Copilot]

The automated code review flagged potential double-frees and memory leaks in the PocketFlow memory management implementation. After analysis, no changes are required - the implementation is correct and verified leak-free.

Memory Model

The implementation uses a dual-responsibility pattern:

• Context owns and frees wrapper pointers (*T) created by context.set()
• Application owns and frees the actual data stored in those wrappers

For complex types like [][]const u8:

// Node creates data → stored in context
const outline = try allocator.alloc([]const u8, 3);
context.set("outline", outline);  // Creates wrapper *[][]const u8

// Manual cleanup frees THE DATA
for (outline) |point| allocator.free(point);
allocator.free(outline);

// Context.deinit() frees THE WRAPPER
// allocator.destroy(typed_ptr)

Why Review Suggestions Would Break Things

1. Removing manual cleanup → memory leaks (actual data never freed)
2. Freeing data in cleanup_exec → use-after-free (next node reads freed context data)
3. Deep cleanup in context destructor → not feasible with type erasure (*anyopaque)

Verification

Tested with GeneralPurposeAllocator in debug mode - zero leaks detected.
