VS Code extension (deferred ΓÇö requires stable event API)

[Ljosmann]

Summary

Visual team monitoring via VS Code extension. Deferred ΓÇö requires stable headless mode + event API from Phase 2.

Architecture Constraints

• Must use IPC to headless Parley process (option b) ΓÇö single-process model can't run in-process in VS Code
• Consume stable CLI/headless interfaces, never re-implement orchestration
• Cross-platform support needed (pop/push/parrot are Windows Terminal-specific today)
• Presentation layer only ΓÇö NOT a second control plane

Prerequisites

• Stable headless mode (Add @copilot coding agent as a Squad member type bradygaster/squad#13)
• Stable telemetry/event API (extract from orchestrator)
• Cross-platform support for pop/push/parrot equivalents

Context

Phase 5 of Dev Tool Integration Strategy (decisions.md 2026-04-13). Highest cost, defer until foundation is solid.
