aicc-py 0.1.0: initial SDK

- protocol.py: pydantic models for all AICC message types (envelope,
  session_init, tool_call, tool_result, event, error, heartbeat)
- bridge.py: Bridge with @bridge.tool registration, capability checks,
  session management, serve_forever
- client.py: AICCClient with single background reader (safe on
  concurrent transports like WebSocket), call_tool, events, manifest
- tool.py: @tool decorator with schema generation from type hints
- schema.py: JSON Schema generation (str/int/float/bool, list, dict,
  Optional, pydantic models)
- transport: Transport protocol, InProcessTransport, WebSocket client+server
- tests: 12 passing (integration, schema, websocket roundtrip)
- examples: bridge_minimal.py + agent_minimal.py (verified end-to-end)
