docs: switch consumer snippets to the BOM and fix wrong artifact IDs

- README and the two tutorials were showing `sk.ainet.transformers:
  llm-core` / `llm-runtime-kllama` / `llm-agent` — these are project
  paths, not the published artifact IDs. The actual published coords
  are `skainet-transformers-core`, `skainet-transformers-runtime-
  kllama`, `skainet-transformers-agent`. Anyone copy-pasting hit a
  resolution failure.
- Switch all three to the BOM pattern so the version pin lives in one
  place; only the BOM line needs bumping per release.
- Add a Maven dependencyManagement example to the Java getting-started
  tutorial since Maven users need the explicit `-jvm` classifier.

+The recommended way to consume is via the BOM. It pins every published `skainet-transformers-*` artifact and re-exports the upstream `sk.ainet:skainet-bom`, so the engine-side `sk.ainet.core:skainet-*` artifacts get the matching version too — you only need to declare the BOM version in one place.
