BedrockPackOptimizer

Losslessly consolidates exact duplicate texture files in a generated Bedrock pack. Bedrock JSON refers to textures by path, so duplicate bytes can share a single canonical file once every exact path reference has been rewritten.

This intentionally does not perform perceptual image matching, PNG re-encoding, or deduplication outside textures/. Only byte-identical images with the same file extension are candidates. If an alias occurs in a malformed JSON file, a non-JSON file, or as part of a larger JSON string, the alias file is retained because that reference cannot be rewritten with full structural confidence.
