[Copilot]

Pull request overview

Refactors and extends build packaging logic to support agent host/Copilot dependencies in remote server (“reh”) builds and to share the same Copilot packaging utilities between desktop and remote build pipelines.

Changes:

• Introduces build/lib/copilot.ts with shared helpers to (a) filter Copilot platform packages during packaging and (b) copy VS Code’s node-pty binaries into Copilot’s expected prebuilds/ locations.
• Updates the desktop packaging gulpfile to use the shared Copilot helpers (removing inline implementations).
• Updates the remote server packaging gulpfile to apply the Copilot exclude filter and to run a post-package step that copies Copilot native deps.

Pull request overview

This PR adjusts VS Code’s build packaging logic to better support Copilot/agent-host dependencies in remote server (REH) and desktop artifacts by centralizing Copilot-specific packaging helpers and applying them to server builds.

Changes:

• Introduces build/lib/copilot.ts to share Copilot packaging utilities across build targets.
• Applies a Copilot exclude filter to REH packaging and reuses the same filter in desktop packaging.
• Adds a REH post-packaging step to copy VS Code’s node-pty binaries into Copilot’s expected prebuilds/ layout.

Pull request overview

This PR updates VS Code’s build/packaging pipeline to better support running the Copilot SDK/CLI in the agent host and remote server (REH) distributions by centralizing Copilot-related packaging logic and ensuring native node-pty binaries are placed where the Copilot runtime expects them.

Changes:

• Add build/lib/copilot.ts helpers for platform/arch normalization, Copilot platform-package filtering, and post-packaging native dependency copying.
• Update desktop packaging (build/gulpfile.vscode.ts) to use the shared helpers and normalized runtime platform/arch naming.
• Update remote server packaging (build/gulpfile.reh.ts) to apply the Copilot exclude filter and run the native dependency copy step after packaging.
