Adding initial version of mosdepth WILDS Docker image

[tefirman]

Type of Change

• New Docker image

Description

Adds a new WILDS Docker image for mosdepth, a fast tool for calculating sequencing coverage depth from BAM/CRAM alignments at per-base, per-region, or windowed resolution (Pedersen & Quinlan, Bioinformatics 2018).

• Tool version: mosdepth 0.3.14 (latest upstream release)
• Base image: ubuntu:24.04
• Install method: Official pre-built static x86_64 binary downloaded from the GitHub release to /usr/local/bin/mosdepth
• Runtime deps (pinned via apt-cache policy): wget, ca-certificates, zlib1g, libbz2-1.0, liblzma5, libcurl4t64 — htslib's compression and HTTPS transitive deps
• Final image size: ~106 MB
• Files added: mosdepth/Dockerfile_latest, mosdepth/Dockerfile_0.3.14, mosdepth/README.md
• Also updated: amd64_only_tools.txt — mosdepth added so the ARM64 build is skipped (see Additional Context)

Testing

How did you test these changes?

• make lint IMAGE=mosdepth — both Dockerfiles pass hadolint with no warnings
• make build_amd64 IMAGE=mosdepth — both Dockerfile_latest and Dockerfile_0.3.14 build successfully and the in-build smoke test mosdepth --version reports mosdepth 0.3.14

Did the tests pass?

Yes. Lint clean, build green, smoke test green on linux/amd64.

Checklist

• Dockerfile follows naming convention (Dockerfile_X.Y.Z or Dockerfile_latest)
• All required OCI metadata labels are present and accurate
• README.md is included/updated in the tool directory
• Tested locally with make validate IMAGE=toolname (or manually built and verified)
• Image builds successfully for target platform(s)

Additional Context

AMD64 only. Upstream mosdepth only publishes a linux/amd64 binary, so mosdepth is added to amd64_only_tools.txt to skip ARM64 builds — same pattern smoove already uses for the mosdepth it bundles.

Relatively basic image, merging without additional review for a Tech Talk demo.
