feat!: replace workflow_run with repository_dispatch for real-time build status updates

Replaces the workflow_run trigger mechanism with repository_dispatch events to enable real-time build status communication between build workflows and the artifact comment system.

Build workflows now actively notify the comment workflow when builds start, complete, or fail, providing immediate status updates rather than polling for completed workflows.

Adds real-time payload processing to display current build status and target information in PR comments, improving visibility into ongoing build processes.

BREAKING CHANGE: Changes the trigger mechanism from workflow_run to repository_dispatch, requiring build workflows to explicitly send status notifications.
