Benchmark: asdf 0.10 vs nvm 0.40 vs fnm 1.35 for Node.js Version Switching Speed

Node.js developers rely on version managers to switch between runtime versions for different projects. Three popular tools dominate the ecosystem: asdf (general-purpose version manager), nvm (Node Version Manager), and fnm (Fast Node Manager). This benchmark compares the 0.10, 0.40, and 1.35 releases of these tools respectively, focusing on version switching speed and related operations.
