docker: second review pass fixes
- Dockerfile: lift numba past vllm's 0.61.2 pin after the numpy>=2.4 re-upgrade; 0.61.2 refuses numpy 2.3+ at import time and the stack cannot move numpy down. Verified numba 0.65 + numpy 2.4.6 + vllm import cleanly together. - docker-publish.yml: resolve UNSLOTH_ZOO_REF in a step that mirrors the pushed tag only when the tag exists in unsloth-zoo (the zoo currently cuts no tags, so blind mirroring broke every tag publish); falls back to main. - Dockerfile.studio: Studio venv stays on cu128 for arm64 too, matching the base venv (cu130 wheels would lift the driver floor to 580+), and gets the same NVRTC cu13 swap for DGX Spark / GB10 sm_121 support. - docker_confirm.sh: do not drop to CPU mode when docker info lacks a nvidia runtime entry; CDI installs and Docker Desktop WSL2 expose GPUs without one. The phase 3 --gpus probe is now the authority. - docker_confirm.ps1: GPU selector built as an args array; comma device lists get version-aware CSV quoting (native arg passing changed in PowerShell 7.3). - studio_launch.sh: no fixed Jupyter default password; generate a random one and print it when JUPYTER_PASSWORD is unset. Env snapshot for SSH sessions now written via shlex.quote instead of sed so values with quotes or command substitution cannot break or inject into /etc/profile.d. - install.ps1: honour UNSLOTH_TORCH_INDEX_FAMILY like install.sh does.
