Implements Phase 1 of US-509. Adds the `warp init` subcommand with `--template` and `--path` flags, a template registry with scaffold() function, and embedded template content for async-rust, async-go, and async-ts templates. Includes unit tests for scaffolding, error cases, and file structure validation. Closes #68 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Creates tests/fixtures/async-rust-template/ with a complete Rust async handler project that compiles to wasm32-unknown-unknown and produces a valid WASI component exporting warpgrid:shim/async-handler@0.1.0. Updates the CLI template embedding to include all 8 WIT files via include_str!, the panic handler, and the [workspace] opt-out. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Creates tests/fixtures/async-go-template/ with a Go async handler using the warpgrid-go/http bridge pattern. Includes main.go with health and echo endpoints, main_test.go with httptest-based unit tests, go.mod, warp.toml, and README. Updates CLI async_go.rs template embedding with all fixture files including test file. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Creates tests/fixtures/async-ts-template/ with a TypeScript async handler using the fetch event pattern. Includes handler.ts, package.json, warp.toml, README, and the full WASI 0.2.3 + WarpGrid shim WIT deps tree required by ComponentizeJS. Updates CLI async_ts.rs template to embed all 37 WIT dep files via include_str!, ensuring scaffolded projects are self-contained. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Creates integration_async_templates.rs with tests that validate: - Rust template builds to wasm32, converts to WASI component, exports warpgrid:shim/async-handler, loads into WarpGridEngine, and handles health + echo requests correctly - Go template fixture structure validation (TinyGo build test available but marked #[ignore] since it requires TinyGo) - TS template fixture structure validation (jco build test available but marked #[ignore] since it requires ComponentizeJS) 5 tests pass, 2 ignored (require external toolchains). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds tests that scaffold each template to a temp directory and verify the generated files match the corresponding fixture directory content. This catches drift between embedded templates and test fixtures. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
