🐛 Bug Fixes

Fixed SMTP Configuration Issues (#26)

• SMTP Username Validation: Removed email format requirement from SMTP username field
• Better Provider Support: Now supports SMTP providers like Resend that use non-email usernames (e.g., "resend" + API key)
• Improved UX: Updated placeholder text to clarify "username or email" format

Enhanced Template Loading (#13)

• ARM64 Compatibility: Added robust template loading with better error handling for ARM64 architecture
• Fallback System: Implements graceful fallback to ensure application continues working even with template parsing issues
• Detailed Logging: Better error messages for troubleshooting template problems

Currency Display Consistency (#16, #14)

• Fixed Hardcoded Symbols: Replaced hardcoded "$" with dynamic currency symbols from settings
• Global Consistency: All subscription cost displays now respect user's currency preference

Documentation Improvements (#32)

• Known Limitations: Added clear documentation about price history limitations
• User Guidance: Explains that annual calculations use current prices, not historical spending data

🔧 Development Improvements

CI/CD Pipeline Optimization

• Efficient Builds: Docker images now only build/push on merge to main and version tags, not on PRs
• Proper Tagging: Version tags (e.g., v0.4.0) now create corresponding Docker tags (0.4.0, 0.4)
• PR Testing: Separate workflow for PR validation with Go tests and Docker build verification
• Resource Optimization: Reduced unnecessary Docker builds on pull requests

Testing Infrastructure

• Playwright Integration: Added comprehensive end-to-end testing with Playwright
• Automated Validation: Tests for subscription calculations, form submissions, and UI consistency
• Multi-browser Support: Configured for Chrome, Firefox, and WebKit testing

📊 Verified Calculations

• Monthly/Annual Totals: Confirmed accuracy of subscription calculations including annual subscriptions converted to monthly equivalents
• Category Breakdown: Verified that spending by category correctly shows monthly equivalents (e.g., $37/year → $3.08/month in Education category)
