- New target: copilot.ts — writes MCP server entries to ~/.copilot/mcp-config.json (global) or ./.mcp.json (local) - Shared-config cascade: uninstallTargets detects when multiple targets share .mcp.json and skips redundant removal + warns - Claude local detection no longer uses .mcp.json as a signal (shared with Copilot) — only .claude/ directory - Copilot local detection uses ~/.copilot dir, not .mcp.json, to avoid false positives when only Claude/Cursor local is set up - Tests: 6 new cases covering install, sibling preservation, uninstall, printConfig, and registry lookup - README/CHANGELOG/CLI descriptions updated

Summary
Add GitHub Copilot CLI as a supported installer target.
codegraph install --target=copilotnow configures the Copilot CLI agent, writing MCP server entries to~/.copilot/mcp-config.json(global) or./.mcp.json(local/workspace).Changes
src/installer/targets/copilot.ts— install/uninstall/detect/printConfig for Copilot CLI, usingmcpServersJSON format (same shape as Claude Code, Cursor, Kiro).uninstallTargetsnow detects when multiple targets share the same config file (e.g..mcp.jsonis used by both Claude Code and Copilot CLI for local installs). When one target removes thecodegraphentry, subsequent targets that also write to that file are reported as cascade-removed with a warning — instead of silently double-deleting.detect()no longer uses.mcp.jsonexistence as a local-installed signal (since it's shared infrastructure). Only.claude/directory is used. This prevents false positives when only Copilot local is installed.~/.copilotdirectory (not.mcp.json) to detect whether Copilot CLI is installed locally, avoiding false positives when only Claude/Cursor local is set up.Tests
