Description

Two related issues exist with scheduled task failure events:

1. **Original Issue:**The ScheduledTaskFailed event doesn't dispatch consistently across all failure modes (exceptions, non-zero exit codes, background/system failures). While [12.x]ScheduledTaskFailed not dispatched on scheduled task failing #55572 addressed part of this, there's still inconsistent behavior. thus it was reverted.

2. **New runInBackground Issue:**When using ->runInBackground(), commands don't properly return status codes, causing exceptions in the scheduler. This prevents proper failure event dispatching for background tasks.

Steps to Reproduce

For Issue #1:

// routes/console.php
Artisan::command('failing-command', function () {
    throw new Exception('Should trigger failure event');
})->everyMinute();

// AppServiceProvider.php
Event::listen(ScheduledTaskFailed::class, function () {
    Log::error('Failure event not received');
});

For Issue #2:

// routes/console.php
Schedule::command('app:command-exit')
    ->everyTenSeconds()
    ->runInBackground(); // Causes exceptions

Expected Behavior

1. All task failures (including background jobs) should dispatch ScheduledTaskFailed

2. Background tasks should properly report their status without throwing scheduler exceptions

Actual Behavior

1. Some failure modes still don't trigger the event

2. Background tasks cause scheduler exceptions instead of clean failure reporting

Root Cause

1. Incomplete failure state handling in the scheduler's execution flow

2. Background process status checking isn't properly integrated with the event system

Suggested Solution

Need to:

1. Expand the scheduler's failure detection to cover all edge cases

2. Properly handle background process status returns

3. Ensure consistent event dispatching regardless of execution method

Steps To Reproduce

// routes/console.php
Artisan::command('failing-command', function () {
    throw new Exception('Should trigger failure event');
})->everyMinute();

// AppServiceProvider.php
Event::listen(ScheduledTaskFailed::class, function () {
    Log::error('Failure event not received');
});

and for the second issue

// routes/console.php
Schedule::command('app:command-exit')
    ->everyTenSeconds()
    ->runInBackground(); // Causes exceptions
