Update Docker Script

[2vibeornot2vibe]

What changed:

1. Auto detects package manager to accommodate for more distros (assuming docker is already installed and configured)
2. Skips docker build if the image already exists, allowing offline operation
3. Changed NVIDIA runtime test to runtime version 12.8.1, since 12.4 is not on docker.io anymore
4. Mount cache dir to /tmp (tmpfs-backed on newer distros) instead of ~/.cache for speedups
5. HuggingFace connectivity check, auto-switch to HF-Mirror if failed
6. Uses sdpa attention if CUDA Arch<=7.0 since sage's main branch will not work

(PS: it's just some quick and dirty fixes with the help of gemma-4 to make it work on my Arch setup, more improvements are definitely needed for this script)

thx

1. you removed the former docker script, does the new one cover at least what the other one did ?
2. why is the support for cuda 12.8 and not for cuda 13 / pytorch 2.10 (official current wangp config)

1. Yes it does. I tried to change the name of the script (because it now covers more than just debian-based distros), which resulted in the original script being removed.
2. The original script uses an even older version (12.4) to ensure compatibility with pre-Turing cards, as CUDA 13 dropped support for those. Also the original script checks for CUDA 12.4 runtime every time on startup, but a later merged PR for the Dockerfile updated that to 12.8 with pytorch 2.10, causing a version mismatch. This is just a quick fix to make that check pass again :)
