[GothwadTech]

What was broken

• Bottom bar covered the whole screen. GothwadBottomBar's row used heightIn(min = 80.dp) and every tab item used fillMaxHeight(). Inside a Scaffold the row is measured with the full screen as its max height, so the bar grew to the entire screen: it sat over the header and the page content got zero height (<em>"kuch dikh hi nahi raha"</em>).
• Search tab had no bottom bar — it was navigated with a special case and was not wrapped in TabShell.
• Profile tab had no bottom bar and no top bar / status-bar padding — AccountScreen rendered a bare LazyColumn.

What changed

• Bottom bar row is now a fixed 72dp (height(72.dp)), tab items are vertically centred (icon 32dp + label), so the bar never expands and the Scaffold gives the content the remaining space.
• Search is a normal tab: wrapped in TabShell, same save/restore nav options as the other tabs, and it now renders inside GothwadScaffold so the tab bar stays visible.
• Profile (AccountScreen) now uses GothwadScaffold with a "Profile" top bar (downloads + settings actions) and correct insets, so the bottom bar is visible there too.
• Search idle screen reordered: last 5 recent searches on top → 5 suggested apps → Recently viewed at the very bottom. Recently viewed ids are persisted in DataStore (Settings.recentlyViewed, newest first, max 10) and recorded when an app detail opens.
• Theme is now sky blue #0494F4 (the launcher-icon blue): primary + containers in light/dark, banner gradient #0494F4 → #00C6FF, icon palette, launcher/splash accent (gothwad_accent). Brand-named palette entries (Brand/BrandDark/BrandLight/BrandContainer/BrandInk) replace the old Green* names so green cannot creep back in. Selected chips, segmented controls, install-progress rings and the info banner now use the brand container; semantic success/installed badges stay green.
