munit 1.0.0-M6 hangs forever with scala-cli test

Describe the bug
When I run scala-cli test math.test.scala that was written with munit 1.0.0-M6 then the process hangs (forever?)

To Reproduce
put this code in math.test.scala

//> using lib "org.scalameta::munit:1.0.0-M6"

class MathSuite extends munit.FunSuite:
  test("addition") {
    assert(1 + 1 == 2)
  }

  test("multiplication") {
    assert(3 * 7 == 21)
  }

scala-cli test math.test.scala
Compiling project (test, Scala 3.2.0, JVM)
Compiled project (test, Scala 3.2.0, JVM)
MathSuite:
  + addition 0.01s
  + multiplication 0.001s
# shell hangs here

Expected behaviour
exit scala-cli after test completes, I do not have this issue with munit 0.7.29

To me, this should be a wontfix on the Scala CLI side. munit shouldn't spawn non-daemon threads when it (apparently) doesn't need to.

@bishabosha Thanks for reporting in Scala CLI. It helps us to fix it in munit by scalameta/munit#606.

It should work from the next release of munit.
