feat(official-bots): activate opening book in expert bot (native-safe)
Load the Polyglot opening book as a classpath resource and wire it into the expert HybridBot. Previously the bot supported Option[PolyglotBook] but BotController passed None, so the book was never used. PolyglotBook.fromResource reads via getResourceAsStream so the book is embedded in the GraalVM native image instead of read from the filesystem (FileInputStream) — no file needs mounting into the pod. The filesystem apply(path) factory is kept for tests. Moved codekiddy.bin into resources as opening_book.bin. Dropped the per-probe debug println.
