I took another pass at getting connectors to output debug logs when running the development environment locally. That's working now! I also noticed that the development automation could be made more accessible to people not familiar with Nix. So I made some quality-of-life improvements:

• fix debug-level logging for MongoDB connectors when running local development services
• get more logs from engine when running local development services
• update readme to link to NDC Hub and to published Docker images
• simplify Nix installation instructions to "use the Determinate Systems installer"
• add a quickstart that gets everything running with one command that does not require setting up a development shell first
• simplify instructions for setting up the development shell
• instead of asking developers to install nix-direnv themselves, install it automatically with a snippet in .envrc
• update justfile recipes so that developers don't need to set up a development shell to run the recipes
• add justfile recipes for running development services locally
