llm-echo 0.5

llm-echo 0.5 is a debug plugin that echoes prompts instead of querying an LLM. The update adds realistic token accounting for tool calls, system prompts, and reasoning steps, improving simulation accuracy for developers testing LLM workflows. This helps refine cost estimates and debugging in local LLM environments.
