467ac9d98a feat: add support for CommandElabM at #eval 
Note that it does not use `MetaEval` to execute the term of type
`CommandEval`. Thus, we can now use `#eval` to execute simple commands.

see #1256

3ed910a043 refactor: rename AsyncList.asyncTail to delayed 
I often found the terminology confusing as it is inconsistent with
`List.tail`

ae683af9c2 refactor: merge AsyncList.updateFinishedPrefix/finishedPrefix 
We only ever use both of them together, and forgetting to call the first
one first could lead to subtle bugs.

c3585dbbbb chore: raw syntax kind accesses

c2166fc602 chore: work around parameterized parser syntax kinds 
We should find a better solution for calling parameterized parsers such
as `matchAlt` than these helper definitions that confuse the antiquotations.

d499e67c87 fix: incorrect antiquotation kind annotations 
Apparently, none of them led to incorrect syntax trees, but `TSyntax`
still disapproves.

6c64b1b20b chore: work around for type inference 
It seems type information often flows from the body to the loop
variable, which is problematic with coercions.

5e334b3e90 chore: postpone TSyntax adoption for some parts 
The namespace `TSyntax.Compat` can be opened for a coercion
`Syntax -> TSyntax k` for any `k`, as otherwise this PR would never be done.

498c7a6a97 refactor: remove some unnecessary antiquotation kind annotations 
These are just the ones I stumbled upon, there should be a lot more now
rendered obsolete by the coercions.

a78302243c refactor: strengthen Syntax signatures 
Most notable change: `Quote` is now parameterized by the target kind.
Which means that `Name` etc. could actually have different
implementations for quoting into `term` and `level`, if that need ever
arises.

a12cde41e1 chore: work around macro limitations 
It would be nice if `macro` was as expressive as syntax quotations, but
right now it's not.
