v0.5.0

Added

• register_command tool: creates a persistent custom IAgentCommand from C# source. The command is saved to Assets/AgentBridgeScripts/, compiled by the included asmdef, and discovered via TypeCache after domain reload. Supports string, int, float, and bool parameters with JSON marshaling.

Changed

• Server startup instructions in serve.go now include guidance on register_command for domain-specific tasks that need to run more than once.
