[Copilot]

Pull request overview

Adds GitHub Copilot as a first-class provider across the contracts, server adapter + health checks, and the web UI settings/picker so sessions can be started and monitored using the Copilot CLI/SDK.

Changes:

• Extend shared/contracts provider + model abstractions to include copilot (start options, model options, runtime event sources).
• Add server-side Copilot adapter + registry wiring and health/doctor probes via @github/copilot-sdk.
• Expose Copilot in the web app: provider picker, setup card guidance, settings for binary path/config dir, and custom models.
