feat: add Scala 3.8.4 cross-compilation target (#870)
* feat: add Scala 3.8.4 cross-compilation target for testing
Motivation:
Ensure pekko-management compiles and tests pass on the next Scala 3 release
line.
Modification:
Add scala3NextVersion (3.8.4) to crossScalaVersions and CI matrix.
Result:
CI now tests against Scala 2.13, 3.3, and 3.8.
Tests:
Not run - CI will validate
References:
None - proactive compatibility testing
* fix: keep Scala 3.8.4 cross builds clean
Motivation:\nPrepare the Pekko Scala 3.8.4 cross-build PRs for future Scala
3 LTS upgrades while preserving Scala 2.13.x and Scala 3.3.x compatibility.
Modification:\nScope Scala 3.3-only compiler options correctly and adjust
sources/build settings so Scala 3.8.4 compiles without errors or warnings.
Result:\nThe project cross-builds cleanly across the intended Scala
versions, with Scala 3.8.4 kept warning-free where validated locally.
