refactor: migrate artifact comment system from repository_dispatch to workflow_run

Replaces the repository_dispatch event system with workflow_run triggers to improve reliability and reduce complexity. The new approach automatically detects PR associations through commit SHA lookups rather than requiring manual payload construction.

Removes redundant notification steps from build workflows and simplifies the concurrency group logic. Enhances manual testing support with improved PR discovery fallbacks.
