Enhanced Artifact Pull Logging

Added detailed logging to artifact pull operations that displays file count and total size in human-readable format.

Changes:

• Storage Layer (pkg/storage/pull.go):

  • Added PullStats struct to track FileCount and TotalSize
  • Modified Pull() function to return statistics alongside paths
  • Updated doPull() to collect file size information during downloads

• Command Layer (cmd/pull.go):

  • Enhanced all pull commands (job, workflow, project) to display statistics
  • Added formatBytes() utility for human-readable size formatting
  • Updated function signatures to handle new statistics return value

• Tests (cmd/pull_test.go, pkg/storage/pull_test.go):

  • Added comprehensive unit tests for formatBytes() function
  • Added storage-level tests for statistics tracking
  • Verified integration with existing functionality

Result:

Pull operations now display enhanced logging:

* Remote source: 'path/to/source'.
* Local destination: 'path/to/destination'.
