Make Echo seamless to run locally

[fmhall]

We want Echo to be extremely easy to run locally.

Users should be able to run:

git clone, cd echo, pnpm i, then pnpm dev, and it should work the first time on the majority of machines. Required dependencies, like docker compose, should be clearly defined.

After a user runs pnpm dev, they should be able to navigate to http://localhost:3000/ and have an experience similar to production (https://echo.merit.systems/).

Related to #310

Ask:

• Try running echo locally with a fresh clone
• Any issues or confusions you run into, please log here
• Any pnpm commands that are required but not properly documented, please indicate here (I.e. setting up DBs)
• Make a PR that addresses the issues you ran into, and includes any other quality of life improvements you can find.
• Include best practices in the readme and documentation.

Hi @fmhall can I take on this issue

Hello! @fmhall
i have implemented a one-command automated setup that makes Echo work locally with just pnpm setup - no more manual Docker/PostgreSQL configuration needed.
