BOM 0.23.0 missing `skainet-compile-opt` from `<dependencyManagement>`

[michalharakal]

Summary

sk.ainet:skainet-bom:0.23.0 is missing one published engine module from its <dependencyManagement>: sk.ainet.core:skainet-compile-opt. Same gap was present in 0.22.2 (noted as a follow-up on #584); didn't make it into the 0.23.0 release.

Evidence

The artifact exists on Central:

$ curl -s "https://repo.maven.apache.org/maven2/sk/ainet/core/skainet-compile-opt/" | grep -oE 'href="0\.23[^"]*"'
href="0.23.0/"

$ curl -sI https://repo.maven.apache.org/maven2/sk/ainet/core/skainet-compile-opt/0.23.0/skainet-compile-opt-0.23.0.pom
HTTP/2 200

But it is not enumerated in the BOM POM (https://repo.maven.apache.org/maven2/sk/ainet/skainet-bom/0.23.0/skainet-bom-0.23.0.pom). The BOM lists 16 modules; skainet-compile-opt is not among them.

Effect

When a downstream uses the BOM and pulls in something that transitively requests skainet-compile-opt:0.21.0 (e.g. via skainet-transformers-inference-bert:0.21.1), Gradle resolves it at 0.21.0 instead of upgrading to 0.23.0, leaving a single-artifact version skew across an otherwise consistent 0.23.0 engine.

Reproduced just now in michalharakal/SKaiNET-leaf-cli:

implementation(platform("sk.ainet:skainet-bom:0.23.0"))
implementation("sk.ainet.transformers:skainet-transformers-inference-bert:0.21.1")

./gradlew dependencies --configuration runtimeClasspath:

+--- sk.ainet:skainet-bom:0.23.0
|    +--- sk.ainet.core:skainet-compile-dag:0.21.0  -> 0.23.0
|    +--- sk.ainet.core:skainet-compile-opt:0.21.0  ← stays at 0.21.0
|    +--- sk.ainet.core:skainet-io-core:0.21.0       -> 0.23.0
|    +--- sk.ainet.core:skainet-lang-core:0.21.0     -> 0.23.0
... (rest correctly upgraded by the BOM)

Suggested fix

Add the missing entry to the BOM build script and ship a 0.23.1 patch:

api("sk.ainet.core:skainet-compile-opt:0.23.1")

While at it, a sweep against https://repo.maven.apache.org/maven2/sk/ainet/core/ would catch any other published module that's not in the BOM. Right now the BOM lists 16 modules but core/ ships more — worth diffing in the same patch.

Acceptance

• https://repo.maven.apache.org/maven2/sk/ainet/skainet-bom/<patch>/skainet-bom-<patch>.pom includes skainet-compile-opt.
• Reproducer above shows skainet-compile-opt:0.21.0 -> <patch> instead of staying at 0.21.0.
