v3.0.0

[3.0.0] - 2025-09-18

Added

• Modular services: TemplateDiscovery, TemplateCacheManager, DynamicRegistry, TemplateInvalidator.
• Documentation: Added docs/SERVICES.md detailed architecture & advanced usage guide.
• Batch & namespace invalidation APIs: invalidateTemplates(), invalidateNamespace() + CLI twig:invalidate:batch.
• Unregister APIs: unregisterFunction(), unregisterFilter(), unregisterExtension().
• Runtime cache toggle: disableCache(), enableCache(), isCacheEnabled().
• Namespace auto-escape mapping: setAutoescapeForNamespace(), removeAutoescapeForNamespace().
• Persistent compile index & listing: listTemplates() with status and compile-index.json storage.
• CLI utilities: twig:list, twig:stats.
• Pattern & namespace filtering in listTemplates().

Changed

• Internal monolithic Twig class refactored into facade delegating to new services.
• Batch invalidation optimized to single directory traversal.
• Logging standardized to event=twig.* key=value format using global log_message().
• README expanded for new runtime, listing & invalidation features.

Removed

• Internal PSR-3 logger property & setLogger() method (replaced by helper logging).
• Direct access to internal compiled template arrays (now encapsulated in services).
