/**
 * adapters/copilot-cli — GitHub Copilot CLI adapter.
 *
 * Native config:
 *   - MCP:   $COPILOT_HOME/mcp-config.json or ~/.copilot/mcp-config.json
 *            under root key `mcpServers`.
 *   - Hooks: $COPILOT_HOME/hooks/context-mode.json or
 *            ~/.copilot/hooks/context-mode.json.
 *
 * Hooks use Copilot CLI's native camelCase event keys (preToolUse /
 * postToolUse / sessionStart / userPromptSubmitted / agentStop / preCompact)
 * with flat `{ type, command }` entries. (The CLI also accepts PascalCase
 * event names alongside camelCase — copilot-cli changelog.md:1065 — so the
 * casing is not load-bearing; we use camelCase because it is the CLI's native
 * naming.) Copilot CLI's command output contract is top-level
 * (`permissionDecision`, `modifiedArgs`, `additionalContext`), so this adapter
 * overrides the response formatter from CopilotBaseAdapter.
