Description

Version and Platform (required):

Binary Ninja Version: 6.0.10526-dev
Edition: Ultimate
OS: macOS
OS Version: 26.6
CPU Architecture: arm64

Bug Description:
I compiled the arch_arm64 plugin standalone and installed it into BN_USER_DIR/plugins, and now none of the aarch64 platforms have been registered. It seems that platform_linux/_windows/etc are loaded before my user arch_arm64 and therefore load without considering it and don't create platforms for it.

Steps To Reproduce:

Disable corePlugins.architectures.aarch64
Compile arch/arm64 and install the plugin as normal
Open binja
Console: Platform["linux-aarch64"]
Observe: KeyError: "'linux-aarch64' is not a valid platform"

Expected Behavior:
I expected the Platform to load with my user plugin override.

Additional Information:
This is a regression from 5.3 stable.

Workaround: Compile all of the platform plugins manually and install them as user plugins, too.

Research direction

Start by reproducing the missing linux-aarch64 platform with corePlugins.architectures.aarch64 disabled and a user-installed arch/arm64 plugin. Trace the loading order for arch_arm64 and the platform_linux/platform_windows plugins, then verify that Platform["linux-aarch64"] succeeds without compiling platform plugins manually.
