fyi.opensocial.templateVersion

One version of a published template, as it was put out: never changed, so a tab that names it gets what was chosen. Its files are the template itself, as a folder of it has them: `template.html` (the page, drawn in a sandboxed frame with the site kit in front of it), `SKILL.md` (how to use it, for an agent), `outside.js` and `outside.html` (its public page, if its tabs can have one), `methods/<name>.js` with `lexicons/<name>.json` (the methods it brings, each a query every tab made from it answers under that tab's own namespace), and `lexicons/<nsid>.json` (kinds of record it makes up).
