fix: Handle gracefully when trying to detect invalid sketch name error and folder is missing on filesystem (#1616)

- feat: generalized Node.js error handling
    - Gracefully handle when the sketch folder has been deleted
 - feat: spare detecting invalid sketch name error
    - The invalid sketch name detection requires at least one extra FS access.
       Do not try to detect the invalid sketch name error, but use the original
       `NotFound` from the CLI.
 - fix: typo

Closes #1596
