Claude Code 2.1.131 fixes Windows activation, Mantle auth

ANNOUNCEMENT PRODUCT GITHUB PRODUCT HUNT X

Claude Code 2.1.131 is a small but practical CLI release. The main fixes restore VS Code extension activation on Windows by addressing a bundled SDK path issue, and repair Mantle endpoint authentication when the `x-api-key` header is missing. The update also tweaks the CLI surface by adding `claude-empty-` and removing `claude-empty-D` and `claude-mythos-preview`, which suggests ongoing cleanup of model aliases and exposed options.

// ANALYSIS

Good maintenance release, especially for users on Windows or those hitting Mantle auth edge cases.

–The Windows fix is the most user-visible change because it unblocks the VS Code extension in a common environment.
–The Mantle authentication fix closes a request-path regression that could break API calls in setups relying on implicit auth handling.
–The CLI model surface changes look like housekeeping, but they matter for automation and scripts that depend on stable model names.
–Overall, this reads like a reliability release rather than a feature release, with high value for existing Claude Code users.
