Module merge 

Merge command — combines multiple 3MF files into a single output file.

This module implements the core merge engine for the 3mf merge command. The merge pipeline:

1. Expand glob patterns in inputs
2. Load all input files with full attachments
3. Check for secure content (signing/encryption) — error if found
4. Compute ID offset for each file (max ID in merged so far + 1)
5. Remap all ResourceId cross-references in each model
6. Merge attachments with path deduplication
7. Update texture/displacement paths after attachment remap
8. Combine all resources into one merged Model
9. Apply placement (plate-per-file or single-plate)
10. Write merged model to output
