Claude Code 2.1.142 review: fast mode now defaults to Opus 4.7

The brief

2.1.142 switches fast mode to Opus 4.7 by default, with an env override to pin Opus 4.6.

Key points

  1. Also: a plugin cache cleanup race fix, MCP_TOOL_TIMEOUT honored properly, and cleaner daemon exits on binary upgrades.
