Added a netframework deps command that builds and prints a dependency tree for .NET Framework projects. It finds containing solutions, resolves .csproj references, and displays the tree structure. Useful for understanding project dependencies in legacy codebases.

Enhanced the run command with positional parameter support — run add can now define named parameters that get substituted at runtime, making custom commands more flexible. Also added elapsed time printing after each run completes, so you can see how long commands take.

Fixed npm install detection to work through fnm and nvm version manager wrappers.
