build(setup): rename PyPI package to omy and update publisher metadata

[Qubitium]

What does this PR do?

Fixes the failed release upload (https://github.com/ModelCloud/OMY/actions/runs/33034447184/job/98393998013) caused by the PyPI package name still being transformers, which the configured PYPI_KEY cannot publish to.

Updates setup.py:

• name: transformers → omy
• author: The Hugging Face team ... → ModelCloud + Qubitium
• author_email: transformers@huggingface.co → qubitium@modelcloud.ai
• url: https://github.com/huggingface/transformers → https://github.com/ModelCloud/OMY
• description and keywords updated to mention OMY / Open Model Yard.

The wheel is now built as omy-*.whl and can be uploaded to the omy PyPI project.

Who can review?

Anyone from the ModelCloud team can review.

CI Security Gate — automatic approval blocked

This PR was not automatically approved for CI because the security gate failed.

Possible reasons:

• The PR touches 50 or more files — only PRs with fewer than 50 changed files are automatically approved
• A changed file is outside the allowed directories (src/, tests/, docs/, utils/), has a disallowed extension (only .py, .txt, .md permitted outside tests/ and docs/), or is not .md/.yml inside docs/ — this covers files the PR deletes or renames, not only the ones it edits
• A new high-severity security issue was detected in the changed Python files (Bandit check)
• The PR touches a path this repository protects from untrusted PRs, such as the file that decides who reviews it — a maintainer must make that change in a separate PR

See the workflow run for the exact violations.

A maintainer can review and manually approve CI if a finding is a false positive.
