Skill Tool Built-in Slash Command Invocation

Description

v2.1.108 capability: the model can now discover and invoke built-in slash commands (/init, /review, /security-review) via the Skill tool. Skills can now trigger built-in commands programmatically — collapsing the distinction between user-authored skills and Anthropic-shipped commands inside the tool dispatch layer.
