What does this PR do?

It dedups files during the pack operation.

The use case that wasn't handled before is when the same binary file can have many links pointing to it. Like one binary alias is full and human-readable, and the other is a short alias to access the same binary.

How did you verify your code works?

  • built local version
  • wrote and ran tests
  • packaged my ali-token-summary with the newly built bun and confirmed npm reports a smaller size
