**Problem**
It's been a while since Coursier has been the default library management engine,
and we don't need to support two.
**Solution**
This removes `useCoursier` setting.
**Problem**
We want a more flexible way of aggregating subprojects.
**Solution**
This implements a subproject filtering as a replacement of
the subproject axis in the act command.
**Problem**
Since Scala cross building works better than the plugin cross building `^^`,
it was common for plugin authors to encode plugin cross building as Scala cross building
given that we usually have zero or one sbt release in one Scala version.
**Solution**
This brings in the setting into SbtPlugin so plugin authors can cross build
using sbt 2.x.
**Problem**
The new common settings feature doesn't work when the root isn't created by the user.
**Solution**
This fixes common settings by calling `expandCommonSettingsPerBase(...)` on
the synthetic root's base first.
**Problem**
There's been previous attempt like 1878 to skip publishing of the root,
but it seems like the behavior has regressed at some point in time.
**Solution**
This skips publishing on synthetic aggregate root project.
**Problem**
`run` currently blocks all other commands, such as BSP commands.
**Solution**
`run` no longer blocks the command execution loop.
Instead it pauses the prompt on the current command channel.
**Problem**
testQuick currently does not invalidate on argument changes.
**Solution**
This includes test argument digests.

**Problem**
During sbt 1.x we created scripted-sbt-redux for package name change.
**Solution**
We can move the module back to scripted-sbt, which simplifies things.
**Problem**
Current implementation of testQuick depends on the concept of timestamp,
which probably won't work well with the new consistent analysis store or
the idea of remote caching.
**Solution**
This is a step towards cached testing by making the incrementality hermetic
(no longer depends on the timestamp). Instead this calculates the aggregated
SHA-256 of the class files involved in the test.
`clean` should delete the packed dir. If it does not,
the next `compileIncremental`, which is a cache hit, will see that
the packed dir is already there and will not unpack it.
