* Represents a breadcrumb context with the main entity and optional suffix nodes.
*
* A breadcrumb context consists of:
* - A main context (record or resource) that determines the base breadcrumb trail
* - Optional suffix nodes that are appended after the main trail
*
* Suffix nodes are useful for:
* - "New Record" indicators when creating records
* - "Edit Multiple" indicators when editing multiple records
* - Custom action indicators
*
* Example usage:
*
* // Edit existing record
* $context = new BreadcrumbContext($record, []);
*
* // Create new record (shows: Pages > Parent Page > "Create New Content")
* $suffixNode = new BreadcrumbNode(identifier: 'new', label: 'Create New Content');
