Method global_tool_restricting_skills

core/src/skills/registry.rs:258–270

Instruction skills that actively constrain normal session tool use. Built-in skills have local allowlists for explicit `Skill` invocation, but those allowlists must not make the default registry globally read-only. If a user replaces a built-in name through registration or a skill directory, the replacement is no longer considered built-in.
