* Remove derived state from state classes
* Create provider for derived state
Derived state is automatically stored to memory storage, but can be derived from any observable.
* Fixup state provider method definitions
* Test `DefaultDerivedState`
* remove implementation notes
* Write docs for derived state
* fixup derived state provider types
* Implement buffered delayUntil operator
* Move state types to a common module
* Move mock ports to centra location
* Alias DerivedStateDependency type
* Add dependencies to browser
* Prefer internal rxjs operators for ref counting
* WIP
* Ensure complete on subjects
* Foreground/background messaging for browser
Defers work for browser to the background
* Test foreground port behaviors
* Inject foreground and background derived state services
* remove unnecessary class field
* Adhere to required options
* Add dderived state to CLI
* Prefer type definition in type parameters to options
* Prefer instance method
* Implements factory methods for common uses
* Remove nothing test
* Remove share subject reference
Share manages connector subjects internally and will reuse them until
refcount is 0 and the cleanup time has passed. Saving our own reference
just risks memory leaks without real testability benefits.
* Fix interaction state
