fix: mobile subagent dropdown — single-tap restore, position at top

- Move subagent dropdown to top (near badge) instead of bottom on mobile
- Fix iOS double-tap issue: wrap :hover styles in @media(hover:hover)
- Pin dropdown immediately on first tap (prevent mouseleave auto-close)
- Hide subagents panel by default on mobile (floating windows sufficient)
- Revert broken mobile auto-minimize (agents auto-pop up again)
