Prerelease: no

Release notes: This is a patch release for ONNX Runtime 1.24, containing bug fixes and execution provider updates.

Bug Fixes

• Core: Added PCI bus fallback for Linux GPU device discovery in containerized environments (e.g., AKS/Kubernetes) where nvidia-drm is not loaded but GPU PCI devices are still exposed via sysfs. (#27591)
• Plugin EP: Fixed null pointer dereference when iterating output spans in GetOutputIndex. (#27644)
• Plugin EP: Fixed bug that incorrectly assigned duplicate MetaDef IDs to fused nodes in different GraphViews (e.g., then/else branches of an If node), causing session creation to fail with a conflicting kernel error. (#27666)

Execution Provider Updates

• QNN EP: Enabled offline x64 compilation with memhandle IO type by deferring rpcmem library loading to inference time. (#27479)
• QNN EP: Reverted QNN SDK logging verbosity changes that caused segmentation faults on backend destruction. (#27650)

Build and Infrastructure

• Python: Updated python_requires from >=3.10 to >=3.11 to reflect dropped Python 3.10 support. (#27354)
• Build: Replaced __builtin_ia32_tpause with the compiler-portable _tpause intrinsic to fix cross-compiler portability issues between GCC and LLVM. (#27607)
