fix: invalid Go version format in agfs-server go.mod

[aeromomo]

go.mod specifies 'go 1.25.1' but Go only supports two-component version directives (MAJOR.MINOR). The three-component format causes 'go mod tidy' and builds to fail with:

go: invalid go version '1.25.1': must match format 1.N

This blocks pip install of OpenViking on any system that needs to compile the AGFS server component.

Fix: Change 'go 1.25.1' to 'go 1.25' to match Go's version spec.
