[WIP] Refactor everything server to be more modular and use recommended APIs.

* Adding prompts (simple, complex, with completions)

* Add prompts/simple.ts
  - in addSimplePrompt()
    - register a simple prompt with no arguments

* Add prompts/complex.ts
  - in addComplexPrompt()
    - define promptArgsSchema containing a required city arg of type string and an optional state arg of type state
    - register the complex prompt with a prompt callback that combines the city and state into a prompt asking for the weather in that location

* Add prompts/completions.ts
  - in addPromptWithCompletions()
    - define promptArgsSchema containing department and name string fields with completion handlers
    - register the completable prompt with a prompt callback that combines the inputs into a prompt asking to promote the selected name to head of the selected department

* Add prompts/index.ts
  - import addSimplePrompt, addComplexPrompt, and addPromptWithCompletions
  - export registerPrompts function
  - in registerPrompts()
    - call addSimplePrompt
    - call addComplexPrompt
    - call addPromptWithCompletions

* In package.json
  - add prettier devDependency
  - add prettier:check script
  - add prettier:fix script
  - in build script, copy docs folder to dist

* All other changes were prettier formatting
