Publish official JSON Schema for settings.json

Describe the feature or problem you'd like to solve

publish an official JSON Schema for ~/.copilot/settings.json

Proposed solution

Please publish an official JSON Schema for ~/.copilot/settings.json.

The file has a growing number of settings, but editors currently can't provide reliable autocomplete, descriptions, or validation (although acknowledging this is configurable via the CLI itself under /config /settings , it would just additional quality of life enhancement to have schema available if prefer to edit inline the settings.json directly for some key/value validation)
Similar tools, including Claude Code, publish schemas for their settings files, which makes configuration much easier to discover and edit correctly.

Proposed solution:
Provide a maintained JSON Schema for ~/.copilot/settings.json, ideally available through SchemaStore.

首先，盘点 CLI 的 /config 和 /settings 命令所公开的设置，然后将其与 ~/.copilot/settings.json 配置进行比较。当一个得到维护的官方 JSON Schema 提供设置描述、自动补全和验证，并考虑通过 SchemaStore 发布时，即视为完成。
