Great work.

TestHandleCollationMessageDeclare and TestHandleCollationMessageAdvertiseCollation failed.
It seems you have nil context in the Run method of CollatorProtocolValidatorSide, and that is why it panics

Otherwise, everything looks good to me.
You can merge once you fix these tests.

[axaysagathiya]

in both the tests,

If you set context in CollatorProtocolValidatorSide{}, code will not panic
(Workaround)

	ctx, cancel := context.WithCancel(context.Background())
	cpvs := CollatorProtocolValidatorSide{
		ctx:            ctx,
		cancel:         cancel,
			...
	}
