(Discuss) Add boundaries / exclusions to scope plugins
## Problem/motivation
Follow-up to:
#3586195
Boundaries / exclusions were discussed quite a bit in the past, but hasn't been implemented yet.
Example context item:
- Tone and voice
- Scope
- Use case = Writing Words
- Entity bundle = exclude for Support Notes (content type)
Translation: The context will be applicable to any agent subscription with use case = writing words unless it's a node that's a Support Notes content type
## Solution
Add an exclusion option for each scope item and bake that into the logic
Could be a dropdown per scope item:
- None (neutral/default)
- Include
- Exclude
## Timing
This doesn't have to be in 1.0 if we don't have time, but it would be nice to introduce it as soon as possible.
