/**
* Reads React's internal fiber pointer directly off a native view instance and walks up to the
* root, storing both under window.__serverDrawerFiberRoot/__serverDrawerFiberSelf for Eval scripts
* to search afterward. Same technique Key Inspector's own Settings-screen capture uses, but kept
* under separate globals - Key Inspector's capture only reaches whatever tree its own Settings
* screen renders in (very likely a separate native modal/root from MainTabs' guild tab content),
* so a capture point actually inside this plugin's own rendered output is what's needed to reach
* anything under the Guilds tab (confirmed live: a Settings-screen capture couldn't find
* QuestDockWithQuestContext at all, even navigating to the Guilds tab first).

// tab content, so a fiber captured there can never reach anything under the Guilds tab (Quest

// independent searches for Quest Dock components both came up empty even while a real quest was
// visibly rendering on the Guilds screen, and a fiber-tree walk from a Settings-screen capture
// couldn't find QuestDockWithQuestContext at all.
//
// GuildsBar's hidden slot is a reliable alternative capture point: it's confirmed to actually
// mount on the Guilds screen (that's this whole file's job), and it's a sibling of the Quest Dock
// in the same tree (both live under MainTabsNavigatorPanel), so walking up from here and back down
// reaches Quest Dock correctly. Stored under the same window.__keyInspectorFiberRoot/
// __keyInspectorFiberSelf globals Key Inspector's Eval scripts already expect, so no existing
// script needs to change - this just gives them a capture point that's actually reachable.
