fix: Clearer error message for cast(▸) notation
...
The old error message said:
```
throwError "invalid `▸` notation,
expected type{indentExpr expectedType}\ndoes contain
equation left-hand-side nor right-hand-side{indentExpr heqType}"
```
The phrase `does contain ... nor ..` seems gramatically incorrect.
What was (probably) intended was `does **not** contain ... nor ...`.
We take the opportunity to clean up the error message and
be clearer that the equality does not contain the expected result type.

feat: improve isDefEq for projections
...
When solving `a.i =?= b.i`, we first reduce `a` and `b` without using
delta reduction. If at least one become a structure, we reduce the
projection. Otherwise, we try to solve `a =?= b`, only reduce `a.i`
and `b.i` if it fails.
