fix: onboarding libraries to Librarian / automl, run, and iam

[suztomo]

Summary

Onboards 4 libraries from OwlBot to Librarian (v0.40.1-0.20260904160715-39fbb3f6fecb) using gapic-generator-cloud 0.52.0 (#36532):

1. google-cloud-automl-v1 (unblocked by gapic-generator-ruby#1340 / librarian#7465)
2. google-cloud-automl-v1beta1 (unblocked by gapic-generator-ruby#1340 / librarian#7465)
3. google-cloud-run-client (unblocked by ruby-cloud-renamed-from=google-cloud-run in librarian#7500 & gapic-generator-ruby#1342 / librarian#7447)
4. google-iam-client (unblocked by ruby-cloud-renamed-from=google-iam in librarian#7500 & gapic-generator-ruby#1342 / librarian#7447)

Analysis of Code Diffs

Standard Expected Changes

• OwlBot Removal: Deleted .OwlBot.yaml, .owlbot-manifest.json, and custom .owlbot.rb scripts across all 4 libraries.
• File Permissions: Snippet script permissions standardized from 100755 to 100644 (librarian#7057).
• Library Metadata & Documentation Titles:
  • google-cloud-automl-v1beta1/google-cloud-automl-v1beta1.gemspec: Description updated to match service.yaml summary (Train high-quality custom machine learning models with minimum effort and machine learning expertise.).
  • google-cloud-run-client: .yardopts, README.md, and google-cloud-run-client.gemspec title/description updated to match google/cloud/run/v2/run_v2.yaml (Cloud Run Admin API).
  • google-iam-client: .yardopts, README.md, and google-iam-client.gemspec title/description updated to match google/iam/v2/iam_v2.yaml (Identity and Access Management (IAM) API).

Generator & Formatter Improvements (Verified Behaviors)

• Split URL Rejoining in Proto Docs (google-cloud-automl-v1beta1):
  • In google-cloud-automl-v1beta1/proto_docs/google/cloud/automl/v1beta1/io.rb, URLs split across lines in proto comments (https:\n//cloud.google.com/...) are automatically rejoined into valid single-line Markdown links (https://cloud.google.com/...) via FormattingUtils.format_doc_lines (gapic-generator-ruby#1340).
• Native Gem Renaming Support (google-cloud-run-client & google-iam-client):
  • Previously, .owlbot.rb post-processing scripts manually renamed google-cloud-run -> google-cloud-run-client and google-iam -> google-iam-client. With ruby-cloud-renamed-from (librarian#7500 and gapic-generator-ruby#1342), the generator natively outputs the renamed gemspec, entrypoint (lib/google-cloud-run-client.rb, lib/google-iam-client.rb), and version constants (Google::Cloud::Run::Client::VERSION, Google::Iam::Client::VERSION) without .owlbot.rb.

Checking to see whether I can add the compute libraries here too.

Checking to see whether I can add the compute libraries here too.

Let's keep the google-cloud-compute and google-cloud-compute-v1 library migration separate because of in-flight proto definition updates #36350.

Is the format change a result of Librarian auto-generation?

[suztomo]

Yes, this is consistent with other libraries to have upper-case.
