Instead of creating a new path over and over again, we can instead push the node before the next loop starts, then pop it when we're done.
Instead of always calling `.splice()`, there are cases where if we replace a node with a single other note that we can replace it directly without using `splice(…)`.

This PR is a tiny improvement to the
walk(…)implementations, not a super bigdeal but thought about something and was pleasently surprised that it did have
an impact.
The idea is twofold:
pathto the current node. This re-uses the existingpatharray and pushes the current node before the recursive call and pops it afterwards. This way we don't need to allocate a new array for each recursive call. Testing this on Tailwind UI means ~14k fewer allocations..splice(…), we can directly update a single value in the array if we are replacing a node with another node.Testing on the Tailwind UI codebase, this results in:
