Claude Code v2.1.217 → v2.1.218: /code-review now runs as background subagent

[claude-yolo]

WHY you should care

/code-review no longer fills your conversation context — it runs as a background subagent now. This means stacked slash commands keep their review target correctly, and your conversation stays clean.

Also notable:

• 🚀 Emoji shortcode autocomplete (:heart: → ❤️, disable with emojiCompletionEnabled)
• Fixed background session isolation not canonicalizing symlinked working directories (potential workspace escape)
• Fixed auto-compact never triggering for Claude Opus 4.8 on Bedrock
• Fixed corporate mTLS, TLS-verify, OAuth scope, and proxy settings being ignored in Claude Desktop sessions
• Fixed Windows auto-update failures that could leave claude.exe missing
• Windows path corruption fix: C:\Users\unicorn no longer gets mangled into CJK characters
• Fixed left arrow key discarding conversation with no undo
• MCP claude mcp list now shows HTTP status on connect failures

PRs

• #1087 (v2.1.218 - forked skills run in background by default, /code-review now a subagent)
• #1088 (v2.1.218 - /code-review runs in background + new context-window-exceeded stop reason)
