Qwen3.5 jinja template to run superpowers on opencode

qwen35-relaxed.jinja

{# 
  Qwen3.5-compatible relaxed chat template
  Purpose:
  - allow multiple system messages
  - treat developer messages like system messages
  - merge all leading/interleaved system/developer messages into one system block
  - avoid "System message must be at the beginning"
