nook.freno.me/agents listed twelve agents and said "twelve" in its meta
description, OG title and intro, while the app's registry (AgentSpec.all)
gained Muse in 0.10.0 as its thirteenth. The page mirrors that registry
by hand from another repo, so nothing flagged the drift.
Adds the Muse card from its plugin manifest and registry row: the plugin
body at ~/.nook/plugins/muse installed through Muse's own plugins CLI,
its fourteen hook events, approvals answerable from a card (every tool
call under Verify), and this Mac only since remote hosts skip it. The
positioning claims table and copy move to thirteen with it.
Tests: src/routes/nook/agents.test.ts pins the roster to the registry's
names in order (red on master: Muse missing) and every stated count to
the number of entries (red when the intro says twelve again).
