If a Micropub h-entry post's title matches an existing article that's
still a draft, update that article in place rather than trying to
insert a duplicate. If it matches one that's already published,
reject the request with a clear error instead of silently colliding.
Also set includeTrashed on Article's slug config as a safety net: this
model soft-deletes, and Sluggable's uniqueness check ignores trashed
rows by default, so a previously-deleted article's title could crash
new inserts with a raw unique constraint violation (this is exactly
what surfaced in Flare as a UniqueConstraintViolationException on
articles_titleurl_unique once the prior swallowed-exception fix
shipped).
