New gates let Claude Code report tools that exist but are switched off as "available if turned on"

What

When Claude Code can't find a requested tool, it now has a new check for whether the tool actually exists but is currently disabled by remote configuration. If a gate called tengu_gleaming_cupcake is on and the session isn't running under HIPAA restrictions, such disabled tools are counted separately in the tool-resolution results. A second, separate gate called tengu_joyful_anchor supplies an allow-list of tool names used for a related decision elsewhere.

Why

This is groundwork for telling a user or model that a missing tool isn't unavailable outright, but rather switched off and could be turned on, rather than treating it as simply nonexistent.
