Problem Description

The current --inspect-electron flag does not take into account electron's --inspect-brk flag, documented here: https://www.electronjs.org/docs/tutorial/debugging-main-process#--inspect-brkport

So there is no way to debug issues that might crop up on process start, making it very frustrating to debug complex issues that might occur.

Proposed Solution

Change inspect to the same syntax, --inspect/--inspect-brk and deprecate the old flag.

Alternatives Considered

Add another flag --inspect-brk-electron.
