* externalize interface compatibility for two optional template engines
Templ and GoStar are currently module dependencies for Golang SDK. They
should not be required for 1.0 release. This step replaces two component
interfaces with copies that ensure compatibility without having to
include various optional engines as dependencies with each Datastar
deployment.
* update comments and documentation for Golang SDK
Added comments to `execute.go` file. I will make similar changes to
other files. I submit those as a way of getting feedback.
The only public API change is the removal of execute script options
struct. It is changed to private by letter case because the options
pattern is used to configure script execution. The struct serves no
purpose and pollutes the public API.
* add hot reload example to Golang SDK
Updated the Golang SDK README.md file to include a list of examples that
will be expanded in the future. A basic example is moved into its own
directory. A hot reload example is added alongside it.
