• add OpenAI-compatible chat/completions, OpenAI responses, and Anthropic messages endpoint support
• add vision proxy warning notices, diagnostics, output logging, i18n, and endpoint testing UI

Verification

• npm run format:check
• npm run compile
• npm run lint
• git diff --check

Pull request overview

This PR introduces a configurable “Vision Proxy” system so the extension can convert image attachments into text (via either a VS Code vision-capable LM or a user-configured HTTP endpoint) before forwarding the request to DeepSeek.

Changes:

• Added a Vision Proxy configuration webview (source selection, endpoint settings, API key handling, and connection testing).
• Implemented endpoint-based vision adapters (OpenAI Chat Completions, OpenAI Responses, Anthropic Messages) with structured diagnostics/errors and custom header support.
• Refactored vision resolution to use a VisionDescriber abstraction and to surface “missing/failure” notices into the initial response.
