[Code Quality] Create gold standard feature implementation checklist from branch-prefix analysis

[github-actions]

Description

The Gold Standard: branch-prefix Feature Implementation Analysis (#12838) provides an exemplary reference for end-to-end feature consistency across schema, implementation, testing, and documentation. Create a developer guide that codifies these patterns for future feature development.

Suggested Changes

Create a new document at docs/development/gold-standard-checklist.md (or similar location) that includes:

Content Structure

1. Introduction: Reference the branch-prefix analysis as the gold standard example

2. Schema-Implementation-Documentation Checklist (from the analysis):

   • Schema: Define all constraints (type, minLength, maxLength, pattern, enum)
   • Schema: Document reserved keywords and business rules in description
   • Implementation: Enforce ALL schema constraints with explicit checks
   • Implementation: Use pre-compiled regexes matching schema patterns exactly
   • Implementation: Provide clear, actionable error messages with actual values
   • Tests: Boundary testing for numeric constraints
   • Tests: Valid and invalid cases for patterns
   • Tests: Case sensitivity testing for reserved keywords
   • Tests: Integration tests for feature usage
   • Docs: State all constraints in prose
   • Docs: Provide usage examples
   • Docs: Document default behavior
   • Usage: Use feature in real workflows to validate UX

3. Example Walkthrough: Summarize the branch-prefix feature as a reference implementation

4. Common Anti-Patterns: What to avoid when implementing new features

Files Affected

• New file: docs/development/gold-standard-checklist.md (or similar path)
• Optional: Link from CONTRIBUTING.md or DEVGUIDE.md

Success Criteria

• Checklist document created with all items from the analysis
• Document explains why each checklist item matters
• Example references link to the branch-prefix analysis
• Document is discoverable by contributors (linked from existing guides)
