feat: Add Changelog Management System for TestFlight Releases

[graycreate]

Summary

This PR implements a comprehensive changelog management system that automatically extracts version-specific release notes from CHANGELOG.md and uses them in TestFlight releases.

Changes

1. CHANGELOG.md - New changelog file with:

   • Structured format for version history
   • Current v1.1.1 entries populated from git history
   • Clear instructions for maintaining changelog

2. fastlane/changelog_helper.rb - Ruby module that:

   • Extracts changelog for specific version from CHANGELOG.md
   • Validates that changelog entry exists before release
   • Formats content for TestFlight (converts numbered lists to bullets)
   • Handles 4000-character TestFlight limit

3. fastlane/Fastfile - Updated to:

   • Import and use changelog_helper
   • Validate changelog exists before building
   • Extract version-specific changelog
   • Pass changelog to TestFlight upload

4. CLAUDE.md - Added documentation:

   • Complete version and changelog workflow
   • Step-by-step release process
   • Fastlane command reference

How It Works

Before this PR:

• All TestFlight releases showed: "Bug fixes and improvements"

After this PR:

• Automatically extracts version-specific changelog
• Fails build if CHANGELOG.md missing entry for current version
• Formats changelog properly for TestFlight display

Example Workflow

When releasing version 1.2.0:

1. Update V2er/Config/Version.xcconfig:

   MARKETING_VERSION = 1.2.0
   

2. Update CHANGELOG.md:

   ## v1.2.0
   1. Feature: New awesome feature
   2. Fix: Critical bug fix

3. Commit and push - CI will automatically:

   • Validate changelog exists
   • Extract changelog for v1.2.0
   • Upload to TestFlight with proper release notes

Testing

✅ Tested changelog extraction locally:

• Successfully extracts v1.1.1 changelog
• Converts numbered lists to bullets
• Handles missing versions gracefully

Benefits

• 📝 Better communication - Testers see specific changes
• 🔒 Enforced documentation - Build fails without changelog
• 🚀 Automated process - No manual TestFlight edits needed
• 📊 Version history - CHANGELOG.md provides clear project history
