v0.18.1

Changed

• Restyled live subagent rendering, async widgets, and background completion notifications with compact Claude-style visual grammar while preserving existing observability paths.
• Parallel subagent result rendering now labels parallel workers as Agent N instead of Step N, while chain rendering keeps step terminology.

Fixed

• /run and single-agent tool calls now allow self-contained agents to run without a task string.
• The subagent tool description no longer advertises hardcoded builtin agent names and management list output now separates disabled builtins from executable agents.
• Flexible subagent tool schema fields now include explicit JSON Schema types so llama.cpp and local OpenAI-compatible providers accept them.
• Settings package sources now resolve explicit git: and npm: entries from project and user package caches.
• Slash-command subagent results are now export-friendly, including completed output and child session paths in visible export content.
