feat: implement v2 3-tier architecture (mcpctl → mcplocal → mcpd)

- Rename local-proxy to mcplocal with HTTP server, LLM pipeline, mcpd discovery
- Add LLM pre-processing: token estimation, filter cache, metrics, Gemini CLI + DeepSeek providers
- Add mcpd auth (login/logout) and MCP proxy endpoints
- Update CLI: dual URLs (mcplocalUrl/mcpdUrl), auth commands, --direct flag
- Add tiered health monitoring, shell completions, e2e integration tests
- 57 test files, 597 tests passing
