release: 0.1.10 — balance widget actually shows + avatar ring

Balance pill was rendering nothing for admin/root accounts because
mcp-server's §4 returns HEICODE_USER_NOT_FOUND for users that never
came through from-agnet onboarding. Fall back to Heicode NewAPI's
own /api/user/self when that happens; reshape into the same envelope
so the UI is path-agnostic.

New balanceStore (zustand) — single polling loop, BalanceBar +
avatar ring share it. AppShell starts it once auth bootstraps.
BalanceBar now shows a "loading…" placeholder on first fetch so
the widget is visible from frame one.

SidebarUserCard avatar wears an SVG ring whose arc length tracks
remaining/(remaining+used) and color hits the same green→amber→red
thresholds as the bar.

Manager: /desktop-client drops the manifest-notes wall of text, the
old HEICODE_DESKTOP_FILE_* subtitle goes away, and a Mac fallback
entry is always spliced in when the live manifest is Win-only.
