1.5.4: the text follows the rename, and a check keeps it that way

Kristian read the readme and found it still telling people to configure the
plugin under WooCommerce, for a page that moved to the Nolimit menu three
releases ago. Sweeping for it found seven stale places, and three of them are
notices THE PLUGIN SHOWS THE USER — the missing-WooCommerce notice, the
activation error and the incomplete-install warning all still called it
WooCommerce Email Discount Manager.

That is the mimir.guide failure exactly: the code moved, the text stood still,
and nothing failed. It was found by somebody reading, which is the only way it
could be found, and that is the argument for the check rather than for being
more careful next time.

ci/static.sh now asserts two things. The name in readme.txt's title matches the
Plugin Name header, because the header is what WordPress shows and everything
else has to agree with it. And no shipped PHP file contains OLD_PLUGIN_NAME,
which is now a value in ci/plugin.conf rather than a habit.

The changelog is deliberately exempt: an entry describes what was true for that
release, and rewriting it would be a different lie. Only text describing the
CURRENT state is checked.

Both halves proven red — a readme title that disagrees, and the old name put
back into one notice.

Not changed: the page stays under Nolimit rather than gaining a second entry
under WooCommerce. One menu is the family's shape, and a duplicate entry is
clutter rather than a fix for a readme that was simply wrong.
