Should we add a CLI tool?

[AmitoVrito]

Would a synapsekit CLI be useful?

synapsekit init          # scaffold a new project
synapsekit run rag       # run a RAG pipeline interactively
synapsekit run agent     # run an agent with tools
synapsekit graph export  # export graph as Mermaid/DOT
synapsekit bench         # benchmark your pipeline

Would you use this? What commands would you want?
