Subject: [PATCH] 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.

(cherry picked from commit bf6dba878e514ca40726467867911a07d5c8a5a2)
