Initial implementation of claude-max-bridge

OpenAI-compatible FastAPI server wrapping the Claude Code CLI.
Translates /v1/chat/completions requests into claude --print subprocess
calls using stream-json input/output for multi-turn support and real
streaming deltas.

Features:
- Full multi-turn conversation support via --input-format stream-json
- Real-time streaming with --include-partial-messages delta tracking
- Rate limit (429) and auth error (401) detection from CLI stderr
- Configurable timeout, graceful subprocess cleanup on disconnect
- /v1/models endpoint and /health check
