fix: correct docker workspace path in task prompt

[hobostay]

Summary

• Fix raw string literal bug in trae_agent.py:133 where r"[Project root path]:\workspace\n\n" produced incorrect output

Problem

The raw string prefix r on line 133 caused two bugs:

1. \n was NOT interpreted as newlines — producing literal \n characters in the prompt text sent to the LLM
2. The workspace path used \workspace (backslash) instead of /workspace (forward slash), which is incorrect for Docker containers running Linux

Fix

Changed r"[Project root path]:\workspace\n\n" to "[Project root path]:/workspace\n\n"

Test plan

• Run agent with docker config and verify the prompt contains proper newlines and /workspace path
