Implement automated template update system with GitHub Copilot integration

[Copilot]

This PR replaces the manual 5-step template update process with a fully automated GitHub Copilot-powered system that preserves all custom sections while providing users with simple copy-paste templates for issue creation.

Problem

The current template update process in README.md (lines 64-72) required users to manually:

1. Check for updates in the repository
2. Compare versions between local and remote
3. Download and replace the template
4. Review changes to understand improvements
5. Test for compatibility

This manual process was error-prone and didn't guarantee preservation of [CUSTOMIZE] sections containing project-specific content.

Solution

🤖 Automated Issue Templates

Created two ready-to-use templates in the new templates/ directory:

• automated-template-update.md: Comprehensive workflow with detailed validation steps
• copy-paste-template.md: Quick template for simple copy-paste issue creation

Users can now create a GitHub issue, paste the template content, and GitHub Copilot automatically handles the intelligent merge while preserving all customizations.

📚 Enhanced Documentation

• README.md: Replaced manual update section with automated alternatives, promoting copy-paste approach as recommended method
• docs/setup.md: Added automated update options with both issue-based and direct editor approaches
• docs/automated-updates.md: Complete automation guide with troubleshooting and recovery instructions

🔧 Improved Initial Setup

Enhanced the initial setup instructions to ensure [CUSTOMIZE] sections are properly used from the start, addressing the specific concern about maintaining local configurations during setup.

🛡️ Setup Prerequisites and Content Refinement

• GitHub Copilot Prerequisites: Added setup instructions to ensure GitHub Copilot is active in target repositories before template operations
• Cleaned Custom Sections: Removed duplicate content from custom section examples that was already covered in the main template
• Focused Guidance: Updated examples to emphasize truly project-specific content (custom authentication flows, unique error codes, adapter-specific patterns)

✅ Comprehensive Testing

Added tests/test-automated-templates.sh with 22 tests validating:

• Template file structure and content
• Preservation of [CUSTOMIZE] tag emphasis
• GitHub Copilot instruction inclusion
• Documentation consistency and linking

Key Benefits

• Zero manual steps: Users copy-paste template content into an issue
• Safe customization preservation: All [CUSTOMIZE] sections are automatically preserved
• Intelligent merging: GitHub Copilot handles complex template integration
• Proper setup workflow: Ensures GitHub Copilot is configured before template operations
• Clean content focus: Avoids duplication while maintaining comprehensive guidance
• Audit trail: Issue-based updates create documentation of changes
• Error recovery: Built-in prompts for restoring lost customizations

The automation transforms a complex manual process into a simple workflow: ensure Copilot setup → copy template → create issue → review changes → apply updates.

Fixes #24.
