fix: do not infer type in erase_irrelevant
...
At the time erase_irrelevant is called, we have already eliminated the
`cast`-applications. Therefore non-atomic expressions may no longer
be well-typed (and `infer_type` can fail).

feat: in pure code, do use assume Id monad at do notation
...
This feature produced counterintuitive behavior and confused users.
See discussion at #770 .
As pointed out by @tydeu, it is not too much work to write `Id.run <|`
before the `do` when we want to use the `do` notation in pure code.
