- Add OPENAI_API_TYPE setting (completion/response) with 'completion' as default - Add OPENAI_REASONING_EFFORT setting (minimal/low/medium/high) for Responses API - Add OPENAI_TEXT_VERBOSITY setting (low/medium/high) for Responses API - Add requiresResponsesAPI() function to detect GPT-5 and o-series models - Add chatWithResponsesAPI() function for the new Responses API - Auto-select API based on user setting and model type - Upgrade openai package from v4 to v6 for Responses API support
- add OPENAI_API_TYPE, OPENAI_REASONING_EFFORT, OPENAI_TEXT_VERBOSITY columns - expand notes for each new configuration option - include detailed API type guide for completion vs response - update package.json descriptions and enum values to match new docs - adjust table formatting for better readability in Markdown
- Move OPENAI_API_KEY and GEMINI_API_KEY from settings to SecretStorage - API keys now stored securely using VS Code's SecretStorage API - Keys backed by OS keychain (Keychain/Credential Manager) - Added commands: setOpenAIApiKey, setGeminiApiKey, clearOpenAIApiKey, clearGeminiApiKey - Removed OPENAI_API_KEY and GEMINI_API_KEY from package.json settings - Update README with secure storage documentation Benefits: - Keys never appear in settings.json, logs, or synced settings - Uses OS-level encryption - Independent of workspace configuration

Summary
This PR adds support for GPT-5 and o-series reasoning models using OpenAI's new Responses API, along with secure API key storage using VS Code SecretStorage.
Changes
1. Responses API Support (GPT-5, o-series models)
OpenAI's new Responses API is recommended for GPT-5 and o-series reasoning models. This PR adds three new configuration options:

completion(Chat Completions)response(Responses API)Reasoning Effort Guide:
minimal- Fastest, for simple classification/formattinglow- Quick responses for extraction, short rewritesmedium- Balanced quality/latency/cost (recommended)high- Best accuracy for complex planning/agentsText Verbosity Guide:
low- Compact, concise for UI/chat widgetsmedium- Standard output with reasonable detail (default)high- Verbose for documentation, reports, audits2. Secure API Key Storage
API keys are now stored securely using VS Code's SecretStorage API (backed by OS keychain: Keychain on macOS, Credential Manager on Windows, etc.).
Why SecretStorage?
