    <!--
        The in-game AddOns list (decision 1197) — the ESC-menu half of the AddOns UI, and the
        button `GameMenuFrame.xml` has been carrying as `GameMenuButton_Pending(self, ADDONS)`
        since 0997 ("goes live by deleting one Pending call and writing its OnClick").

        SCOPE — this frame has no reference. 1.12 ships an AddOns list only on the GLUE side
        (`GlueXML/AddonList.xml/.lua`, opened by CharacterSelectAddonsButton); in-world there is
        no such window and the ESC menu has no such entry. This is a deliberate benilla addition
        the director asked for, so nothing here is transcribed and nothing pretends to be. What IS
        borrowed from the reference is the BEHAVIOUR of its glue twin, because it is the same job:

          - the row shape and count: ADDON_BUTTON_HEIGHT = 16, MAX_ADDONS_DISPLAYED = 19
          - AddonList_Update's three-colour title rule — gold loadable, red enabled-but-broken,
            grey disabled (SetTextColor 1/0.78/0, 1/0.1/0.1, 0.5/0.5/0.5)
          - the status column carrying `reason` (our GetAddOnInfo returns the reference's own
            token set — decision 1191 §6)
          - Okay saves, Cancel discards (SaveAddOns / ResetAddOns)

        It is written entirely against the ELEVEN AddOn API verbs 1191 landed — GetNumAddOns,
        GetAddOnInfo, GetAddOnDependencies, EnableAddOn, DisableAddOn, IsAddOnLoaded — with no
        host support of its own. That is the point of it as much as the window is: if this panel
        works, the addon API an addon author would use works, and it is exercised by anyone who
        opens the ESC menu rather than by a test nobody runs.

        WHEN CHANGES TAKE EFFECT — next login, not now. Enabling an addon mid-session would mean
        running its files into a VM that has already fired ADDON_LOADED/VARIABLES_LOADED/
        PLAYER_LOGIN, which is not a state the reference's own loader has a path for; disabling
        one cannot unload it at all. The panel says so on its face rather than leaving a player to
        discover it. The enable state is written at the session's end by the shutdown tail
        (decision 1191 §7, the reference's own last step at 0x490bd0).
