Till JS 56ffcbac39 feat: add Ollama memory optimization, LLM metrics, and chat streaming

Three improvements to the unified LLM infrastructure:

1. Ollama memory optimization (scripts/mac-mini/configure-ollama.sh):
   - OLLAMA_KEEP_ALIVE=5m → models unload after 5min idle (saves 3-16GB RAM)
   - OLLAMA_NUM_PARALLEL=1 → predictable memory usage
   - OLLAMA_MAX_LOADED_MODELS=1 → max 1 model in RAM at a time

2. Request-level metrics in @manacore/shared-llm:
   - LlmRequestMetrics interface (model, latency, tokens, fallback detection)
   - LlmMetricsCollector class with summary stats (for health endpoints)
   - Optional onMetrics callback in LlmModuleOptions
   - Automatic metrics emission in chatMessages() (success + error)

3. Chat streaming (token-by-token SSE):
   - Backend: POST /chat/completions/stream SSE endpoint
   - OllamaService.createStreamingCompletion() via llm.chatStreamMessages()
   - ChatService.createStreamingCompletion() with upfront credit consumption
   - Web: chatApi.createStreamingCompletion() SSE consumer
   - Chat store: sendMessage() now streams tokens into assistant message
   - UI updates reactively as each token arrives
