Is your feature request related to a problem? Please describe:
I always forget to update ports or make sure I am using the correct version of Node when switching projects

Describe the solution:
On shell start:

• check port for updates, or remind if hasn't updated in a while?
  On Change directory:
• if has package.json, check recommended version
• if has .nvm use to change node version

Describe alternatives you've considered:
I could try to remember this on my own each time, but that has proven to not be very often

Links/Additional context:
N/A

Testing:

• Test navigating into new projects with different .nvm versions
• Test starting shell and seeing reminder of port update
