Follow on fixes for #5892

[jamesdaniels]

• Don't allow the devModeHandle if purpose is deploy
• context._name is gone?! Manually pass "purpose" rather than leaning poorly typed options
• Get more defensive w/types
• Rename purpose of "serve" to "emulate"
• Drop the Node 16 check, since v12 is 16+
• Purpose of "test" should default to production target
• Reject the devModeHost if process exits
• Replace old broken e2e test with the new frameworks test

Fixes #5896
