Refactor architect prompt for efficiency and clarity

• Scale thoroughness to task complexity (simple/moderate/complex)
• Reduce unnecessary back-and-forth by encouraging informed decisions
• Emphasize examining codebase before asking questions
• Simplify communication guidelines with direct, professional tone
• Add explicit guidance to avoid pointless confirmations
• Remove verbose examples and focus on actionable patterns
• Move environment info to template variables

This reduces over-planning for simple tasks while maintaining rigor
for complex work, enabling faster task execution.
