add local bindings to context
...
- without this, inside the body of `let x = e in …`, the typechecker
would forget that `x = e`
- now bound variables can reduce, if they have a definition, so RedexTest
needs to take the context too

use constraints when checking δ
...
when checking δ 𝑖 ⇒ s, add 𝑖=ε to Ψ instead of checking s‹ε/𝑖›.
this has the same effect but an error message will show "𝑖, 𝑖=ε" in
the context
