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.

Inizia facendo un inventario delle impostazioni esposte tramite i comandi /config e /settings della CLI, quindi confrontale con la configurazione ~/.copilot/settings.json. Il lavoro sarà considerato completato quando un JSON Schema ufficiale e mantenuto fornirà descrizioni delle impostazioni, completamento automatico e validazione, prendendo in considerazione la pubblicazione tramite SchemaStore.
