Add CLA workflow

[glenn-jocher]

Summary

• add the canonical public CLA workflow with the standard Ultralytics license header
• use ultralytics/actions/cla@main so repositories inherit shared fixes automatically
• route actionable events at the job boundary and grant only actions: write and pull-requests: write
• keep the ledger PAT isolated to the CLA step and central ultralytics/cla repository

Deleted: nothing. No CLA workflow or repository-local equivalent existed; organization-wide CLA enforcement cannot be achieved by deletion or relocation in this repository.

Reused: the canonical ultralytics/actions/.github/workflows/cla.yml structure and shared ultralytics/actions/cla@main implementation.

Validation

• byte-for-byte comparison with the reviewed ultralytics/actions/.github/workflows/cla.yml template
• actionlint .github/workflows/cla.yml
• npx prettier --write .github/workflows/cla.yml
• license-header, shared-main-action, and token-input scan
• git diff --check

The workflow triggers and permission scopes otherwise match the action's required PR-comment and workflow-rerun operations. However, the pinned CLA action revision can overwrite unrelated GitHub Actions bot comments.
