The SDK reaches internal/datetime through settings validation, and that package had only a cgo strftime implementation, so statically linked Tentacle packages could not build. Split the locale-aware cgo formatter into its own file and add a C-locale fallback for builds without cgo. The reader itself still uses the cgo implementation.
