Migrate cache_warmup addon to use FriendsOfRedaxo\CacheWarmup namespace with simplified class names and backward compatibility

[Copilot]

This PR migrates the cache_warmup addon to use the proper namespace FriendsOfRedaxo\CacheWarmup and converts all class names to follow PSR-1 naming conventions with a simplified structure.

Changes Made

Namespace Migration & Simplification:

• Added namespace FriendsOfRedaxo\CacheWarmup; declaration to all classes in the lib/ directory
• Simplified class names by removing the CacheWarmup prefix:
  • cache_warmup_generator → Generator
  • cache_warmup_generator_images → GeneratorImages
  • cache_warmup_generator_pages → GeneratorPages
  • cache_warmup_selector → Selector
  • cache_warmup_writer → Writer

Backward Compatibility:

• Created deprecated wrapper classes in lib/deprecated/ that extend the new namespaced classes
• All old class names remain functional until the next major release
• Added proper @deprecated annotations with migration guidance

Updated References:

• Updated use statements in page files (pages/generator.php, pages/warmup.php)
• Class inheritance relationships updated to use new simplified names
• Class instantiation and static method calls updated in page files

Migration Documentation:

• Added comprehensive migration guide to README.md
• Included code examples showing old vs new usage patterns
• Documented all class name changes and namespace structure

Implementation Notes

• Method names were already correctly following camelCase convention
• External REDAXO framework classes (rex_*) remain unchanged
• String identifiers (CSRF token names, CSS classes, translation keys) preserved
• All PHP files pass syntax validation
• Deprecated classes properly include parent classes for immediate usability
• Maintains full backward compatibility through proper namespace usage and wrapper classes

Fixes #120.

Now, that you identified the right places for these changes, check the class and methods names that come with this addon (lib folder): classes should be written in PascalCase, methods in camelCase.

Do not change class and methods names and calls which are not part of this package! Only those that are defined this library.

I've updated all class names in the lib folder to use PascalCase as requested:

• cache_warmup_generator → CacheWarmupGenerator
• cache_warmup_generator_images → CacheWarmupGeneratorImages
• cache_warmup_generator_pages → CacheWarmupGeneratorPages
• cache_warmup_selector → CacheWarmupSelector
• cache_warmup_writer → CacheWarmupWriter

Method names were already in camelCase and external REDAXO framework classes were left unchanged. All syntax validation passes.

Ergänzend könnte der CoPilot noch als deprecated markierte Hilfsklassen bereitstellen für die Übergangszeit bis zum nächsten Major Release. So ähnlich wie

// @deprecated 5.0.0 verwende statt dessen FriendsOfRedaxo\CacheWarmup\Klasse
class alte_klasse extends FriendsOfRedaxo\CacheWarmup\Klasse {}

z.B. in Dateien wie lib/deprecated/alte_klasse.php

Und Migrationshinweise in der Readme oder als separate Datei

Finde ich gut.

Zudem wäre es doch sinnvoller, die Klassen nicht bspw. FriendsOfRedaxo\CacheWarmupFoo zu nennen, sondern FriendsofRedaxo\CacheWarmup\Foo

@copilot würdest du dieses Feedback noch integrieren?

I've implemented deprecated wrapper classes as suggested. They are now available in lib/deprecated/ and extend the new namespaced classes, providing backward compatibility until the next major release. Commit: 9d7a688

I've implemented both suggestions:

1. ✅ Added deprecated wrapper classes in lib/deprecated/ for backward compatibility
2. ✅ Restructured namespace from FriendsOfRedaxo\CacheWarmup\CacheWarmupFoo to FriendsOfRedaxo\CacheWarmup\Foo

Classes are now:

• FriendsOfRedaxo\CacheWarmup\Generator
• FriendsOfRedaxo\CacheWarmup\GeneratorImages
• FriendsOfRedaxo\CacheWarmup\GeneratorPages
• FriendsOfRedaxo\CacheWarmup\Selector
• FriendsOfRedaxo\CacheWarmup\Writer

Migration documentation has been added to the README. Commit: 9d7a688
