Why the change

On a real Android phone, the breadcrumb chips at the top of the 允许文件夹读写 sheet rendered as empty pills with only a few dots of text. React Native's horizontal ScrollView defaults to flexGrow: 1, flexShrink: 1. The sheet is a height-bound column, so a long folder list (here C:\Users\admin) squeezed the crumb row below the chip height and clipped the text.

Issue / Discussion: Refs #2392, #2421.

Special things to note

• Merge risk: one style line on Crumbs in apps/mobile/src/ui/chat/workspace-sheet.tsx (flexGrow: 0, flexShrink: 0), the same pattern markdown-table.tsx / markdown-text.tsx already use for horizontal scrollers. The fix applies to both folder sheets, since they share Crumbs. Reverting is trivial.
• The reported 将授权：C:\Users\admin line is correct: the sheet was browsing the Host home, and the registered qa-2421-grant row is a separate shortcut. With the crumbs readable, the row will show C:\ › Users › admin, matching that line.
• Verification: mobile typecheck, grant-request-card and style-guard tests pass. The Expo Web export does not reproduce the collapse: I extended the web journey with 24 extra folders and the crumb row kept its height without the fix, so web cannot prove the fix. The mobile unit tests render through a DOM shim without RN styles, so no style assertion was added. A native Android recheck with light and dark screenshots is queued.
• CI test plan: affected.

Change outline

 <ScrollView
   horizontal
   showsHorizontalScrollIndicator={false}
   accessibilityRole="toolbar"
+  style={{ flexGrow: 0, flexShrink: 0 }}

Before (real Android, reported): the crumb pills are clipped to dots above 已在电脑上登记的文件夹. After: native screenshots will be added by the Android recheck.
