Adds `POST /api/v2/templatebuilder/compose/template`, a synchronous endpoint that composes a template from a base and modules, validates it via a provisioner import job, and creates the template in a single request. The handler composes terraform files, bundles them as a tar, inserts the file with hash-based dedup, creates a template version with an import job, waits up to 2 minutes for the job to complete, classifies errors for known failure modes (network-unreachable registry, DNS failures), then creates the template on success. Canceled and failed jobs return appropriate error responses. Also adds `hclwrite.Format` to composed terraform output for canonical HCL formatting. Closes https://linear.app/codercom/issue/DEVEX-279 <details> <summary>Implementation notes</summary> - SDK types and client method in `codersdk/templatebuilder.go` with validation tags matching the standard template creation path (`template_display_name`, `lt=128`) - `ClassifyProvisionerError` in `coderd/templatebuilder/errors.go` detects DNS, connection refused, i/o timeout, and TLS handshake failures and returns actionable messages - `waitForProvisionerJob` polls with a ramp-up interval schedule (100ms, 200ms, 500ms, then 1s steady) and accepts an `onUpdate` callback for future SSE streaming - Audit logging for both template and template version creation - TOCTOU name uniqueness: early check for fast feedback, DB unique constraint catch for the race window (returns 409, not 500) - Swagger annotations for all error responses (400, 404, 409, 504) </details> > 🤖 Generated by Coder Agents
