v0.2.0 — Embedded fleet protocol & permission-aware dispatch

What's new

• Embedded fleet operation protocol as MCP server instructions field — auto-injected into every master LLM request via MCP initialize handshake. No manual protocol setup needed.
• Fire-and-forget fleet_send_message — dispatches prompt and returns immediately. Poll with fleet_get_session_status, retrieve with fleet_get_session_messages.
• fleet_reply_permission — approve/reject slave permission prompts without leaving the chat. fleet_get_session_status now shows pending permissions when blocked.
• Improved tool descriptions with inline workflow guidance for permission handling.
