Add Response Structure Guidelines to agent instructions

[Copilot]

Codifies the 7-part communication structure identified through agent persona exploration research (discussion #12461) that consistently produced high-quality workflow responses.

Changes

New Section: Response Structure Guidelines

Added comprehensive documentation to .github/agents/developer.instructions.md covering:

The 7-Part Structure:

1. Success announcement with contextual emoji (🎉 general, 🚀 deployment, ✨ features, etc.)
2. Deliverables summary with file sizes and descriptions
3. Quick start commands (copy-paste ready, 100% adoption in successful workflows)
4. Key features (4-7 items with checkmarks)
5. Customization options (framework-specific with before/after examples)
6. Pro tips (3-5 actionable insights addressing common pitfalls)
7. Next steps (logical progression: test → deploy → enhance)

Supporting Content:

• Complete template showing all parts flowing together
• 3 real-world examples from high-scoring personas (FE: 4.8/5.0, DevOps: 4.6/5.0, QA: 4.7/5.0)
• Key success factors analysis
• Guidance on when to adapt structure for simple fixes or quick responses

Example Structure

🎉 Successfully created your PR schema review automation workflow!

## What Was Created
- `.github/workflows/pr-schema-reviewer.md` (145 lines) - Main workflow
- `.github/workflows/pr-schema-reviewer.lock.yml` (342 lines) - Compiled workflow

## Quick Start
\`\`\`bash
gh aw compile .github/workflows/pr-schema-reviewer.md
gh aw run pr-schema-reviewer --pr 123
\`\`\`

## Key Features
✅ Validates migration safety (no destructive operations)
✅ Checks for proper indexing on new columns
✅ Comments detailed analysis directly on PR

[... customization, tips, next steps ...]

This formalizes patterns that empirically produce better learning outcomes and user satisfaction.

<issue_title>[plan] Update agent communication template with research insights</issue_title>
<issue_description>## Objective

Formalize the successful communication structure observed in persona exploration research into the agent instructions.

Context

From discussion #12461: Agent responses consistently followed a successful 7-part structure: success announcement, deliverables summary, quick start commands, key features, customization options, pro tips, and next steps. This structure aids learning and consistency.

Approach

1. Add "Response Structure Guidelines" section to .github/instructions/developer.instructions.md

2. Document the 7-part structure observed in successful workflows:

   • Success announcement with emoji (🎉, 🚀, ✨)
   • Deliverables summary (files created with sizes)
   • Quick start commands (copy-paste ready)
   • Key features with checkmarks
   • Customization options (framework-specific)
   • Pro tips section (best practices)
   • Next steps (testing, deployment)

3. Include examples from high-scoring workflows (FE-1, DO-1, QA-1)

4. Specify emoji usage patterns for different contexts

Files to Modify

• Update: .github/instructions/developer.instructions.md
  • Add "Response Structure Guidelines" section
  • Include template with all 7 parts
  • Provide examples from successful workflow responses
  • Add emoji usage recommendations

Acceptance Criteria

• Section documents the complete 7-part structure
• Template shows exact formatting for each section
• 2-3 real examples included from high-scoring workflows
• Emoji usage guidance is clear and context-appropriate
• Template emphasizes copy-paste ready commands (100% adoption rate)
