Summary

• Adds OpenAIAdapter implementing IProviderAdapter
• Installs openai SDK (^6.32.0) in apps/gateway
• register(): initialises OpenAI client with OPENAI_API_KEY, registers codex-gpt-5-4 with Pi ModelRegistry; gracefully skips when key is absent
• listModels(): returns Codex gpt-5.4 (128k context, tools + vision)
• healthCheck(): lightweight GET /v1/models to verify API key validity
• createCompletion(): streaming via chat.completions.create with stream:true; maps chunks to CompletionEvent
• Registers adapter in ProviderService; removes legacy registerOpenAIProvider() method

Test plan

• Typecheck, lint, format:check all pass
• When OPENAI_API_KEY unset: adapter skips, listModels returns empty, healthCheck returns down
• When OPENAI_API_KEY set: codex-gpt-5-4 appears in provider listing

feat(M3-003): implement OpenAI provider adapter for Codex gpt-5.4 ... 6f104d116b

Adds OpenAIAdapter implementing IProviderAdapter, replacing the legacy
registerOpenAIProvider() inline registration in ProviderService.

- Creates apps/gateway/src/agent/adapters/openai.adapter.ts with:
  - register(): initialises OpenAI client, registers codex-gpt-5-4 with
    Pi ModelRegistry using openai-completions API; skips gracefully when
    OPENAI_API_KEY is absent
  - listModels(): returns Codex gpt-5.4 ModelInfo (128k context, tools+vision)
  - healthCheck(): lightweight GET /v1/models to verify API key validity
  - createCompletion(): streaming completions via openai SDK
    chat.completions.create({ stream: true }); maps chunks to CompletionEvent
- Installs openai SDK (^6.32.0) as a dependency in apps/gateway
- Registers OpenAIAdapter in ProviderService alongside OllamaAdapter
- Removes legacy registerOpenAIProvider() private method from ProviderService
