Adds `scripts/templatebuildermodulegen/`, a Go tool that fetches module metadata from the Coder registry HTTP API and generates the `module.json` manifests and `.tf.tmpl` files used by the template builder catalog.
The generator calls `GET /api/modules/{id}` for per-module metadata (display name, description, icon, tags, variables) and the Terraform protocol versions endpoint for semver resolution. No git clone or HCL parsing required.
Split into four files:
- `main.go`: orchestration, module config map, CLI flags
- `types.go`: output types (`ModuleManifest`, `ModuleVariable`) and API response types
- `fetch.go`: HTTP fetching, version resolution, variable conversion, icon normalization
- `write.go`: JSON writer, `.tf.tmpl` Go template and writer
