6704468f07 feat: add coeId instance 
Add an example showing why it is useful.

TODO: reconsider whether we should use the approximation described in
the new test or not.

102d2ae57d fix: avoid unnecessary reduction 
```lean
forallBoundedTelescope `(Nat -> IO Nat) 1 fun xs type => ...
```
should assign `IO Nat` to `type` instead of `IO.RealWorld -> ...`

f34fd3e6b4 refactor: move Closure.lean to Meta 
We will need to improve the support for let-decls. We will use
the new `trackZeta`.

2f4340f63c feat: refine refine tactic 
Now `refine stx` reports an error when there are natural unassigned
metavariables after we elaborate syntax `stx`. The idea is that only
synthetic holes `?<hole-name>` become new goals.
The tactic `refine! stx` implements the Lean3 behavior.

110ae4b571 feat: replace OS-specific stream redirection with pure-Lean Stream redirection 
This avoids the temporary files workaround on macOS and Windows, and makes sure
we can process a `#eval` command and write messages to stdout at the same time.

77b9445544 feat: real ST monad 
@Kha: the new `ST` (and `EST`) are escapable like the Haskell ST monad.
It makes `StateRefT` much more useful because we can now run it from pure
code.

and keep reducing code duplication.
