 * @fileoverview agentHistoryAdapter — converts AgentMessage[] to HistoryItem[].
 *
 * This adapter bridges the sub-agent data model (AgentMessage[] from
 * AgentInteractive) to the shared rendering model (HistoryItem[] consumed by
 * HistoryItemDisplay). It lives in the CLI package so that packages/core types
 * are never coupled to CLI rendering types.
 *
 * ID stability: AgentMessage[] is append-only, so the resulting HistoryItem[]
 * only ever grows. Index-based IDs are therefore stable — Ink's <Static>
 * requires items never shift or be removed, which this guarantees.

 * Convert AgentMessage[] + pendingApprovals into HistoryItem[].

 * Consecutive tool_call / tool_result messages are merged into a single
 * tool_group HistoryItem. pendingApprovals overlays confirmation state so

 *
 * liveOutputs (optional) provides real-time display data for executing tools.
 * shellPids (optional) provides PTY PIDs for interactive shell tools so
 * HistoryItemDisplay can render ShellInputPrompt on the active shell.
