pio-ne-er/Solana-stealth-pumpfun-bundler — reverse-engineered prompt

Build me a working command line tool for Solana that helps launch and manage a Pump.fun token from a small set of wallets. I want a simple menu driven flow where I can presimulate a launch, create the token and pool, run bundled buys across multiple wallets, manually buy or sell from bundler wallets, distribute tokens out to a larger set of holder wallets, gather tokens back later, move SOL between wallets, and check balances for everything.

Please make it use an env file and a settings file for the RPC info, block engine info, wallet keys, token metadata, bundle sizing, timing, and holder distribution amounts. It should be actually runnable, with clear prompts, helpful logs, and good validation when config or wallet files are missing.

I know the wallet mixer, stealth mode, and real bot activity stuff mentioned in the docs is not included here, so do not fake that part. Just make the normal launch, holder distribution, gather, and balance flows solid, and leave clean places to extend later. Look up current docs online if you need to.
