Claude Code 2.1.137 fixes Windows activation

This is a boring update in the right way: AI coding tools win or lose on day-to-day reliability, not just model quality.

• –The only visible change in the upstream changelog is a Windows activation fix, so this is clearly a polish release rather than a product milestone.
• –Small desktop-extension bugs can quietly poison adoption, especially for teams standardizing on Claude Code across mixed OS setups.
• –Frequent patching suggests Anthropic is iterating quickly on the CLI/editor surface, which is exactly where agentic coding tools need to be hardened.
• –No new capability is signaled here, so the signal is operational stability, not a new workflow or benchmark jump.
