Introduces llm.Parse(spec) backed by an extensible Registry that resolves
model strings like "openai/gpt-4o", aliases like "fast", and named targets
like "m5/qwen3:30b" (via LLM_M5 env var DSNs) into ready-to-use *Model
objects. Extension points: RegisterProvider, RegisterAlias, RegisterResolver.

v2 is a new Go module (v2/) with a dramatically simpler API:
- Unified Message type (no more Input marker interface)
- Define[T] for ergonomic tool creation with standard context.Context
- Chat session with automatic tool-call loop (agent loop)
- Streaming via pull-based StreamReader
- MCP one-call connect (MCPStdioServer, MCPHTTPServer, MCPSSEServer)
- Middleware support (logging, retry, timeout, usage tracking)
- Decoupled JSON Schema (map[string]any, no provider coupling)
- Sample tools: WebSearch, Browser, Exec, ReadFile, WriteFile, HTTP
- Providers: OpenAI, Anthropic, Google (all with streaming)
