- Dockerfile: fix glibc 2.41 patch path (cuda-12.9 -> cuda-12.8 to match
installed packages); remove SAGE_ATTENTION_AVAILABLE env var
- sync-build-release.yml: add always() to publish job condition so it runs
even when build-self is skipped (the primary GitHub runner path succeeds),
fixing releases never being created on normal builds
- entrypoint.sh: remove SageAttention compilation and GPU detection logic;
simplify to permissions setup, ComfyUI-Manager sync, custom node install,
and launch
- README: update CUDA version references from 12.9/cu129 to 12.8/cu128;
remove SageAttention documentation; fix docker-compose GPU syntax
