v1.8.0

[1.8.0] - 2026-09-03

Fixed — Android native inference is now real end-to-end

The Android stack previously stopped at placeholder JNI calls and stubbed
HTTP responses. The full chain now runs real tokens:

HTTP → LocalApiServer → LlamaCppBridge → JNI → llama.cpp → GGUF.

• platforms/android/app/src/main/cpp/llama_jni.cpp — rewritten against
  the pinned llama.cpp (b10795) C API: llama_model_load_from_file /
  llama_init_from_model session creation, vocab-based
  llama_tokenize / llama_token_to_piece, llama_decode batching via
  llama_batch_get_one, and a proper sampler chain
  (penalties → top_k → top_p → temp → dist) sampled with
  llama_sampler_sample. Per-session state (ShugoSession: model, context,
  vocab, KV position, pending-UTF-8 buffer) replaces the previous mutable
  globals; nativeDrain flushes partial multi-byte characters at
  end-of-generation so streamed text is never corrupted mid-codepoint.
• CMakeLists.txt — rewritten: valid CMake syntax, static llama/ggml
  linked into libllama_jni.so, optional Vulkan GPU offload
  (-DSHUGOCORE_VULKAN=ON), no -march=native (broke NDK + emulator
  builds), and dual-target support — Android NDK builds and host CI
  validation builds (-DSHUGOCORE_JNI_INCLUDE=...).
• LocalApiServer.kt — replaced JDK-internal com.sun.net.httpserver
  (absent on Android) with a minimal HTTP/1.1 implementation on
  ServerSocket, loopback-only. /api/generate and /api/chat now parse
  JSON bodies, apply sampling options (temperature, top_k, top_p,
  repeat_penalty, seed, num_predict), stream NDJSON chunks when
  stream: true, and return Ollama-shaped responses (response /
  message.content, done, eval_count, total_duration) so ShugoCore's
  OllamaBackend/AndroidBackend work unmodified.

Verified

• Host build of libllama_jni.dylib (full llama.cpp + JNI bridge) compiles
  and links with zero warnings against the pinned headers; all 8 JNI symbols
  (nativeInit, nativeFree, nativeTokenize, nativeDetokenize,
  nativeDrain, nativeEvalPrompt, nativeGenerateToken, nativeReset)
  exported with names exactly matching the Kotlin external fun
  declarations.
• Version metadata aligned at 1.8.0 across version.py, pyproject.toml,
  and build.gradle.
