Pull request overview
This PR addresses #15708 by exposing the distributed application builder pipeline to polyglot AppHosts via standard ATS exports (rather than TypeScript-only generator special-casing), and updates the generated TypeScript surface plus polyglot fixtures to use the shared shape.
Changes:
- Export
IDistributedApplicationPipelinethrough ATS and add ATS-friendlyaddStepandconfigurecapability exports. - Update the TypeScript ATS code generator and snapshot to include the builder-level
pipelinehandle and its methods. - Update TypeScript/Python/Java polyglot AppHost fixtures to exercise the builder-level pipeline API; hide an internal manifest publishing pipeline extension from the polyglot surface.

Description
Fixes #15708 by exposing the builder pipeline through standard ATS exports instead of TypeScript-only generator special casing. This keeps the polyglot AppHost surface aligned across TypeScript, Python, and Java while preserving the existing C# pipeline API.
This change exports
IDistributedApplicationPipeline, adds ATS-friendlyaddStepandconfiguremethods on the pipeline handle, and updates the TypeScript generator snapshot plus the TypeScript, Python, and Java polyglot fixtures to use the shared generated shape. It also explicitly hides the internal manifest publishing pipeline extension from the polyglot surface. During self-review, I fixed a shared TypeScript callback-generation bug in the multi-parameterCancellationTokenpath.Dependencies required for this change: none.
Fixes #15708
