Add a protocol-translating reverse proxy that allows using OpenAI-compatible
API providers (DeepSeek, OpenRouter, Groq, etc.) with Claude Code.
The proxy intercepts Anthropic Messages API requests from the CLI, transforms
them to OpenAI Chat Completions or Responses API format, forwards to the
upstream provider, and transforms streaming/non-streaming responses back.
Key features:
- Request transform: Anthropic Messages → OpenAI Chat/Responses
- Response transform: OpenAI → Anthropic (streaming SSE + non-streaming)
- Provider-agnostic reasoning support (reasoning_content, thinking_blocks,
reasoning fields from DeepSeek, OpenAI o-series, GLM-5, Groq, etc.)
- Event queue pattern for correct Anthropic SSE event ordering
- Two-step test: ① connectivity check ② full proxy pipeline validation
- Desktop UI: API format selector, two-step test results display

Implement a full Provider management layer compatible with Claude Code's settings.json protocol.
- ProviderService: CRUD + activation + settings.json sync + HTTP connectivity test
- Provider REST API: 8 endpoints (list, get, create, update, delete, activate, test)
- API key masking in GET responses (sk-a****xyz)
- Models API refactored to read from active Provider dynamically
- 42 unit tests + 6 real-config integration tests, all passing
