Shared Agent types and message contracts for Rozenite packages.

@rozenite/agent-shared contains the shared type definitions used by Rozenite Agent packages. It defines the Agent tool shape, the message protocol for registering and calling tools, and the shared AGENT_PLUGIN_ID constant used by the bridge packages.

Features

• Shared Tool Types: Common AgentTool and JSON-schema-like input types
• Message Contracts: Typed payloads for register, unregister, call, and result messages
• Single Protocol Constant: Shared AGENT_PLUGIN_ID for the Agent transport
• Package Reuse: Intended for bridge and runtime packages that implement Agent support
