- Introduced atomic claiming mechanism in TaskSchedulerManager to prevent duplicate task executions. - Added CLAIM_TIMEOUT_MINUTES constant to define the timeout for stale claimed tasks. - Implemented releaseStaleClaimedTasks method to release tasks that have been claimed for too long. - Refactored scheduleTasks method to utilize the new atomic claim logic. - Updated ScheduledTask model to include claimed_by and claimed_at fields. - Created migration to add claimed fields to the scheduled_tasks table. - Added tests to ensure atomic claim functionality and stale claim release behavior.

@marcoAntonioNina Laravel already have a feature to prevent overlapping, could you consider to use it to prevent backward compatibility problems: https://laravel.com/docs/12.x/scheduling#preventing-task-overlaps
- Updated the bpmn:timer command in Kernel.php to prevent overlapping executions by adding the withoutOverlapping method with a 5-minute timeout.

Issue & Reproduction Steps
When you have a boundary timer and an email sending configured, the scheduler for some reason starts to duplicate the sendings either because of a delay or because some other task is doing it.
This pull request attempts to prevent another task or the scheduler itself from resending the email.
Solution
How to Test
The process should successfully execute email sending.
Ideally, you should test with a large number of configured ScheduleTasks.
