Improve permission structure and Magisk compatibility + Add root device test workflow

[Copilot]

The customize.sh had multiple issues: incorrect set_perm_recursive usage on individual files, broken shell syntax in gpu_cache_cleaner, and an invalid chmod on system partition. The permission structure was also redundant and conflict-prone.

Permission Structure

• Replaced 45+ redundant per-file set_perm_recursive calls with directory-level permissions
• Added existence checks before applying permissions
• Proper SELinux contexts: vendor_firmware_file, vendor_configs_file, same_process_hal_file
• Removed invalid chmod 644 /system/vendor/firmware/a650_sqe.fw (can't modify system partition)

Magisk Compatibility

• Added debug.angle.rules="" to prevent ANGLE driver conflicts
• Changed ro.zygote.disable_gl_preload=1 → true for consistency

Shell Fixes

• Fixed broken if-else syntax in gpu_cache_cleaner()
• Changed inconsistent echo → ui_print
• Optimized find command with -prune

Root Device Test Workflow

• Added .github/workflows/root-device-test.yml for CI validation
• Validates module structure: module.prop fields, customize.sh syntax, update-binary syntax, directory structure
• Builds test module zip artifact ready for deployment
• Placeholder for future root device tests (test.so files to be added later for OpenGL/Vulkan/OpenCL validation)
• Triggers on push/PR to Magisk Template files, or manually via workflow_dispatch with device/Android version inputs

Before:

set_perm_recursive $MODPATH/system/vendor/lib/libEGL_adreno.so 0 0 0755 0644 u:object_r:same_process_hal_file:s0
set_perm_recursive $MODPATH/system/vendor/lib/libGLESv2_adreno.so 0 0 0755 0644 u:object_r:same_process_hal_file:s0
# ... 40+ more similar lines

After:

if [ -d "$MODPATH/system/vendor/lib" ]; then
    set_perm_recursive $MODPATH/system/vendor/lib 0 0 0755 0644 u:object_r:same_process_hal_file:s0
fi

@copilot also create workflow for root device test (test.so files will be added later.)

@copilot also create workflow for root device test (test.so files will be added later.)

Created the root device test workflow in commit 1cde5e8. The workflow:

• Validates module structure: Checks module.prop fields, customize.sh syntax, update-binary syntax, and directory structure
• Builds test module: Creates a zip artifact ready for deployment
• Root device test placeholder: Ready for test.so files to be added later for OpenGL/Vulkan/OpenCL validation
• Triggers: On push/PR to Magisk Template files, or manually via workflow_dispatch with device/Android version inputs
