refactor(core): move devtools ai tool definition types to primitives

Extract the AI tool definition interfaces from the core debug module to the devtools primitives module. This relocates ToolDefinition, ToolGroup, and DevtoolsToolDiscoveryEvent to the primitives folder, exposing them cleanly via "export type" in the devtools entry point, improving module organization and readability.
