chore(api): DO NOT MERGE - show custom code in SDK reviews

[apcha-oai]

DO NOT MERGE. Draft workflow demonstration; no release or merge is intended.

Make handwritten changes in generated SDK files easier to review. One PR comment shows newly customized files, existing customizations that changed, and commands to inspect the current custom-code diff. It updates in place as the PR changes.

The reporting files come from shared Castiron templates and use normal three-way merges, so repository-specific customizations remain possible. The workflow checks the generated baseline's content hash. Public reporting uses only public snapshot history and needs no private-repository credentials.

This draft is limited to reporting and generation metadata; it does not change the SDK API or runtime. Workflow changes require the repository's normal workflow-write permissions.

Legacy baseline: content hash computed from the pinned checkpoint; not yet recorded in that revision’s stats.
