Fixed "Unknown 'esc_attr' filter" error that occurred when rendering
the product selector template. The issue was caused by WordPress
escaping functions being registered only as Twig functions, not filters.
Changes:
- Added TwigFilter registrations for esc_html, esc_attr, esc_url
- Template now supports both filter syntax (|esc_attr) and function syntax
- Fixes compatibility issues when other plugins use their own Twig instances
- Version bump to 1.1.5
This resolves the bug documented in logs/fatal-errors-2025-12-31.log

CRITICAL BUG FIX: v1.1.1 still had the same error!
Root cause analysis:
- v1.1.1 changed hook to woocommerce_init but error persisted
- Real issue: Settings.php was require_once'd in Plugin::includes()
- At that point, class extends WC_Settings_Page which doesn't exist yet
- Even woocommerce_init fires before WC_Settings_Page is loaded
Solution:
- Removed require_once from Plugin::includes() (line 93)
- Moved require_once to Plugin::add_settings_page() (line 196)
- Settings.php now loads on-demand via woocommerce_get_settings_pages filter
- This filter fires when WooCommerce has loaded all settings classes
Changes:
- includes/Plugin.php: Delayed Settings.php inclusion with explanatory comment
- wc-composable-product.php: Version bump to 1.1.2
- CHANGELOG.md: Documented fix and noted v1.1.1 was insufficient
This addresses the actual root cause that persisted through 3 versions.
