feat(coderd/templatebuilder): author initial module catalog for 19 modules (#26194)

> [!NOTE]
> This PR was authored by Coder Agents on behalf of @jeremyruppel.

Runs the `scripts/modulegen` generator against the coder/registry to produce the initial module catalog for the template builder. Generates `module.json` and `.tf.tmpl` files for 19 modules across four categories:

- **IDE**: code-server, jetbrains, vscode-desktop, vscode-web, cursor, windsurf, zed, kiro
- **AI Agent**: claude-code, aider, goose, amazon-q
- **Source Control**: git-clone, git-config, git-commit-signing
- **Utility**: dotfiles, personalize, filebrowser, jupyterlab

Also updates `catalog_test.go` to validate the new embedded modules load correctly.
