[PFRoux]

PR checklist

Closes issue number #12916

This PR adds a new telomerehunter2 module.

TelomereHunter2 estimates telomere content and telomeric variant repeats from indexed BAM/CRAM sequencing data. It is a Python 3 implementation and extension of the original TelomereHunter workflow.

The module takes a coordinate-sorted BAM file, BAM index and optional chromosome banding file, then emits:

• TelomereHunter2 summary table
• telomeric variant repeat top-context table
• singleton repeat table
• full TelomereHunter2 output directory
• output file index
• version information
