feat: migrate autoCheckUpdates to database with full semver prereleas…

[altaskur]

Description

This PR migrates the autoCheckUpdates preference from localStorage to the database and implements full semver 2.0 comparison with prerelease support, fixing version update detection for alpha releases.

Goal

• Fix update detection system to recognize alpha version increments (e.g., alpha.7 > alpha.6)
• Migrate autoCheckUpdates preference to database for consistency with app architecture
• Ensure SonarQube quality gate compliance and maintain high test coverage

Key Changes

• Added autoCheckUpdates field to AppSettings schema with Prisma migration
• Implemented full semver 2.0 version comparison with prerelease support (alpha, beta, rc)
• Created IPC handlers for autoCheckUpdates with comprehensive test coverage (92%)
• Migrated Angular UpdateService from localStorage to database calls
• Refactored UpdateService to eliminate async constructor operation (SonarQube requirement)
• Updated all test suites for new async initialization pattern
• Added 50+ new test cases for semver prerelease comparison logic

Type of Change

• 🐛 Bug fix (non-breaking change which fixes an issue)
• ✨ New feature (non-breaking change which adds functionality)
• 💥 Breaking change (fix or feature that would cause existing functionality to not work as expected)
• 📝 Documentation update

Impact Assessment

Database Impact

• No database changes
• New migration(s) included
• Existing data migration required

Migration Details:

• Added autoCheckUpdates boolean field to AppSettings table
• Defaults to true for new installations
• Existing users will see default value (no data migration from localStorage)

Backup Impact

• No impact on backups
• Backup format changed
• Restore compatibility maintained

Impact Details:

• Database backups now include autoCheckUpdates preference
• Backup/restore functionality maintains full compatibility
• Setting will be preserved across backup/restore operations

Additional Context

Key Implementation Details:

1. Semver Comparison: Implemented parseVersion() and comparePrereleases() helpers that fully support semver 2.0 specification with proper precedence: release > rc > beta > alpha

2. Database Migration: Created Prisma migration 20260211084714_add_auto_check_updates_to_app_settings with proper defaults and updated template.db

3. IPC Architecture: New handlers in auto-check-updates-handlers.ts with comprehensive error handling and fallback to true on errors

4. SonarQube Compliance: Refactored UpdateService to avoid async operations in constructor, using explicit init() method pattern

5. Test Coverage: Added extensive test coverage for:

   • Prerelease version comparisons (alpha.7 > alpha.6, beta > alpha, etc.)
   • IPC handler database operations
   • Angular service async initialization
   • Error handling and fallback scenarios

Reviewer Notes

Please pay special attention to:

• Semver comparison logic in electron/src/services/update/update.service.ts
• Database migration file and schema changes
• IPC handler implementation and error handling
• UpdateService async initialization pattern (constructor vs init())

All quality gates passed: 1,213 tests, 93.9% Angular coverage, SonarQube quality gate PASSED.
