Console: change __dirname to expected __dirname

Problem: when running `rw c` or `rw c "script"`, the `__dirname` is `/path/to/project/node_modules/compound/lib/server`.
Expected: `__dirname === /path/to/project`

Current workaround: `var dirname = './'`, since `./` points to the correct local dir.

Look at the console command implementation, likely in a file like `lib/server/console.js` or `lib/compound.js`. Find where `__dirname` is used or where the script execution context is set. The goal is to ensure the working directory for scripts run via `rw c` is the project root. Test by running a script that logs `__dirname`.
