[MaxenceGollier]

Following JuliaSmoothOptimizers/.github#18.

Pull request overview

Updates the repository’s breakage CI to rely on JuliaSmoothOptimizers’ organization-wide reusable workflows (per JuliaSmoothOptimizers/.github#18), and removes the now-redundant local breakage implementation.

Changes:

• Replace the in-repo Breakage workflow logic with a call to the org reusable Breakage.yml.
• Add a workflow_run-triggered workflow to post PR comments via the org reusable CommentBreakage.yml.
• Remove the local .breakage helper script and project dependencies that are no longer used.

workflow_run workflows often need explicit permissions because the called reusable workflow cannot elevate the GITHUB_TOKEN. Since this job is intended to comment on PRs (as the workflow name implies), set top-level permissions (e.g., pull-requests: write plus any required actions/contents read scopes for downloading artifacts) so commenting doesn’t fail under read-only default token settings.
