LFDT-Paladin

Upgrades the Go toolchain version across the Paladin workspace. Use when bumping the Go version, fixing CVEs in golang.org/x/* packages that require a newer Go version, or when go.work and go.mod files need updated `go` or `toolchain` directives. Covers all go.mod modules, Dockerfiles, GitHub Actions CI setup, and tooling compatibility (controller-gen).
