feat(vscode): expand custom provider configuration

[chrarnoldus]

Summary

• let custom providers select the OpenAI-compatible, OpenAI Responses, or Anthropic Messages AI SDK package while validating the allowed packages at the extension boundary
• add adaptive thinking, split reasoning, and output effort controls to model variants, including correct edit and unset persistence
• stack variant settings vertically for a clearer configuration layout and keep custom-provider classification consistent across supported packages

Why

Custom endpoints use different AI SDK provider contracts and reasoning options. Exposing these settings in the custom-provider editor avoids manual config changes while preserving safe package selection and reliable deep-merge updates.
