feat(infrastructure): introduce ErrorContext for tracking errors across threads (#83)

* Implement ErrorContext for tracking errors across threads

* reorder Instruction and ErrorContext

* Add ContextType, AppContext, ScreenContext, PtyContext

* Use ArrayVec in ErrorContext

* increase MAX_THREAD_CALL_STACK to 6

* Custom implement Debug for ErrorContext ad ContextType and color output

* Use os_input instead of println!()

* Use array instead of ArrayVec and some cleanup

* Introduce SenderWithContext

* Keep arrayvec at v0.5.1
