fix(docs): correct execution strategy for bug fix workflow

Change complex task strategy from "Brainstorm → Planning → Execution"
to "Use /workflow:plan for structured planning and execution"

Rationale:
- Bug fixes and feature additions typically don't need brainstorming
- /workflow:plan is the appropriate entry point for complex tasks
- Brainstorming is reserved for large-scale architectural changes

Updated in both English and Chinese README files.
