[None][doc] Add AutoDeploy transform registry docs

[danielpolimac]

Summary

• Add explicit AutoDeploy transform API reference sections for BaseTransform, TransformRegistry, and TransformInfo.
• Keep the generated stage pages connected to the registry key workflow used by AutoDeploy transform configs.

Related Issue

Closes #13726

Testing

• python3 -m sphinx -b html docs/source /private/tmp/trtllm-docs-13726-nowarn docs/source/features/auto_deploy/transforms/core.rst

Note: a stricter -W build is blocked by pre-existing repo-wide docs warnings and local autodoc import warnings for missing nvtx; the affected pages render successfully without treating those existing warnings as errors.

Dev Engineer Review

• Added Sphinx API reference sections for BaseTransform, TransformRegistry, and TransformInfo.
• Used autopydantic_model for TransformInfo.
• Included member and inheritance documentation.
• Excluded these entities from the general interface automodule to prevent duplicate documentation.
• Connected generated stage pages to the AutoDeploy registry-key workflow.
• No exported declarations or public API code changed.
• Sphinx HTML and pre-commit checks passed for the modified documentation.
• A warnings-as-errors build remains blocked by pre-existing repository warnings and local nvtx import warnings.

Walkthrough

The transform documentation adds dedicated API sections for BaseTransform, TransformRegistry, and TransformInfo. The general interface reference excludes these entities to prevent duplicate documentation.

Changes

Auto-deploy transform documentation

Layer / File(s)	Summary
Core transform API reference docs/source/features/auto_deploy/transforms/core.rst	Adds autodoc sections for BaseTransform, TransformRegistry, and TransformInfo. The registry section describes transform keys, YAML configuration, implementations, and configuration models. The interface automodule excludes these entities.

Approving — the comments below are optional touch-ups, not blockers.

Docs-only change, and the split into named sections reads better than one flat automodule. Two rendering issues below (pydantic documenter for TransformInfo, and :no-index: on the only definitions of these classes), plus one structural nit.

Suggest verifying by rendering the page and checking that TransformInfo's field descriptions actually appear — the -W-blocked build note doesn't cover this class of problem, since a wrong-but-valid directive produces no warning at all.

[danielpolimac]

Addressed the TransformInfo directive feedback in 2fa115b:

• Switched TransformInfo from autoclass to autopydantic_model while preserving the existing options.

Validation:

• python3 -m sphinx -b html docs/source /private/tmp/trtllm-docs-17633-fix docs/source/features/auto_deploy/transforms/core.rst
• pre-commit run --files docs/source/features/auto_deploy/transforms/core.rst

The Sphinx build succeeded with the same pre-existing repo-wide warnings/local CUDA import warnings noted earlier.

[danielpolimac]

Addressed the remaining documentation review feedback in e3464ee4c0:

• Removed :no-index: from BaseTransform, TransformRegistry, and TransformInfo so they are registered for search and cross-references.
• Added an Other Interface Utilities heading for the remaining interface module members.

Validation:

• pre-commit run --files docs/source/features/auto_deploy/transforms/core.rst
• python3 -m sphinx -b html docs/source /private/tmp/trtllm-docs-17633-review-fix docs/source/features/auto_deploy/transforms/core.rst

The targeted Sphinx build succeeded with the existing repository-wide warnings and local CUDA import warnings.

Status update: current main removed AutoDeploy, including this transform documentation hierarchy, in #19028. The conflict is therefore not meaningfully resolvable without restoring documentation for a removed feature. This PR appears to be superseded by that removal; please confirm whether it should be closed.
