Update every audited reference site to the six renamed skills:
root README headings and links (and drop the jira-jql entry ahead of
its absorption), references/skill-triggers.md rows for jellyfin and
tempest plus four new-name rows for ghost/jira/openlibrary/tmdb,
scripts/grandfathered-skills.txt pruned to the three retained *-cli
entries, pyproject.toml deptry exclusion jellyfin-cli -> jellyfin,
neckbeard routing seams, cli-builder example names, and the lastfm /
verification-methodology eval texts mentioning jellyfin.
