Replace the single utils/github/profile/role_summary.py script with a
focused CLI package split per responsibility (model, logparse, csvio,
render, github, sources). Output format is selectable via --format
(table default, plus markdown, csv, json); source is auto-detected as an
Ansible log, a role-runtimes CSV, or a GitHub Actions run/job URL (CSV
artifacts downloaded via gh).
The compose workflow now writes the CSV as a downloadable artifact and
appends the per-variant markdown to the step summary, and hard-fails
when the log is missing or carries no profile_roles data so a broken
metrics capture can no longer pass silently.
