Built-in capabilities

Kernel tools are the native actions Cerberus can call before any Verba Plugin gets involved.

These tools form Tater's base runtime: local file work, web inspection, memory operations, validation, artifact attachment, and outbound messaging. They are the first half of the smart chaining story before Cerberus hands work off to Verba Plugins.
