refactor(config): simplify configuration file

Removed unused config keys and verbose comments:
- Removed 'middleware' key (not used in codebase)
- Removed 'prometheus.middleware' key (only mentioned in comment)
- Removed 'hooks' arrays (hooks now registered via code, not config)
- Simplified all section comments
- Removed inline comments from config values

The config is now 83 lines shorter while keeping all
functionality that's actually used by the package.

All tests passing.

-    | Hooks allow you to extend the metrics processing pipeline.
-    | Register custom hook classes to enrich or process metrics data.
-    |
-    | Available contexts:
-    | - 'before_record': Before recording job metrics
-    | - 'after_record': After recording job metrics (enrich with custom data)
-    | - 'before_calculate': Before calculating aggregated metrics
-    | - 'after_calculate': After calculating aggregated metrics (export to external systems)
-    | - 'before_baseline': Before baseline calculation
-    | - 'after_baseline': After baseline calculation (trigger autoscaler)
-    |
-    | Example:
-    | 'hooks' => [
-    |     'after_record' => [\App\Hooks\CustomMetricsEnricherHook::class],
-    |     'after_baseline' => [\App\Hooks\AutoscalerTriggerHook::class],
