Cleanup: remove unused in-file symbols across 6 frontend components (~61 LOC)

[FairyPigDev]

Motivation

While auditing the frontend, I found several declared-but-never-referenced symbols (unused destructures, a placeholder array, a dead async helper, a debug console.log inside an unreachable branch). They compile fine today but add noise for new contributors reading these files and make real changes harder to spot in diffs.

I'd like to propose a small, surgical cleanup PR that deletes only the provably-dead symbols — no whole-file deletions, no behaviour changes, no refactors to surrounding code.

Scope

6 files, −61 LOC net. Each removal is a symbol-level delete where the symbol has zero references in its own file and is not re-exported.

File	Removed	LOC
src/components/GlobalSearch/index.tsx	_items fruit-name placeholder array	10
src/components/HistorySidebar/index.tsx	_deleteHistoryTask async helper (never called)	30
src/components/Layout/index.tsx	_setInitState destructure + console.log(chatStore) inside the if (!chatStore) branch	7
src/components/TopBar/index.tsx	{ chatPanelPosition, setChatPanelPosition } destructure, { isInstalling, installationState } + _isInstallationActive block, plus the 2 orphaned store imports	6
src/components/InstallStep/Carousel.tsx	_setInitState destructure + orphaned useAuthStore import	2
src/components/WorkFlow/index.tsx	_handleShare helper + orphaned @/lib/share import	5

Verification

Each symbol was verified dead before removal:

• grep across the file confirms the declaration is the only occurrence.
• For imports that became orphaned after the symbol was removed, grep confirms no other use in the same file.
• No symbol is re-exported, so external callers cannot exist.

Example — TopBar/index.tsx chatPanelPosition:

$ grep -n 'chatPanelPosition\|setChatPanelPosition' src/components/TopBar/index.tsx
61:  const { chatPanelPosition, setChatPanelPosition } = usePageTabStore();

Only the declaration. Zero call sites.

Questions for reviewers

It is ok to open PR to solve this part?
