PAL MCP server adds CLI bridge and subagent features

PAL MCP server (formerly Zen MCP) introduces the clink tool, which connects external CLIs such as Gemini CLI and Codex CLI directly into the current workflow, and supports launching isolated CLI subagents from the current CLI. For example, Claude Code can spawn a Codex subagent to perform code review; the subagent analyzes in a separate context and returns only the final result, keeping the main session's context window unpolluted. Subagents support role specialization (e.g. planner, code reviewer) and full CLI capabilities (web search, file inspection, MCP tool access). For developers running Claude Code or Codex CLI on large projects, clink uses context isolation and role specialization to keep the main session focused on core tasks, while offloading heavy work like code review and bug hunting to subagents. Combined with multi-model consensus and planning tools, teams can achieve seamless handoff from multi-model review to implementation.
