chore(deps): bump skainet to 0.23.0

Picks up:

- The K/N `createRandomAccessSource` POSIX-pread implementation
  (SKaiNET PR #591), so K/N consumers can now load GGUFs above the
  ~2 GiB Kotlin `ByteArray` ceiling. Combined with this repo's
  existing `randomAccessProvider` factory overloads on
  `*NetworkLoader.fromGguf(...)` and the `fromRandomAccessSource(...)`
  variant on `GGUFTokenizer`, downstream native CLIs / consumers can
  switch to the streaming path mechanically.
- Lazy zero-init for parameter placeholders (SKaiNET PR #588), which
  ends real-model load-time OOMs in the DSL builders that this repo's
  loaders sit on top of.

No source changes — purely a version pin bump. Verified by compiling
:llm-runtime:kllama (JVM + macosArm64), :llm-agent (JVM),
:llm-inference:llama (JVM), :llm-inference:qwen (JVM) against the
new dep set.
