Adds step 8 ("Publish to Ghost") so the skill no longer stops at "file
saved to disk" — generating and publishing are one workflow, not two.
Replaces the speculative "Future: Publishing via Ghost Admin API"
section with the operational contract for the now-existing
publish_to_ghost.py script. Updates the slug reference in prose to
match the script (default-newsletter), adds Robotics to the trigger
list, and fixes a stray quote on the robotics/ table row.

ADMIN_BASE pointed at thefulfillment.org (a parked domain) instead of
the actual Ghost host blog.the-fulfillment.org, and NEWSLETTER_SLUG was
"the-fulfillment" instead of Ghost's auto-generated "default-newsletter"
(the display name "The Fulfillment" doesn't determine the slug).
