Tycho v0.9.0

Highlights

• Make multiserver Agents and Projects persistent in Remote UI, with
  server-qualified resources, bounded peer refresh, stale last-good snapshots,
  and explicit peer cache removal.
• Introduce the Remote UI design system across Settings, forms, menus, status
  badges, confirmations, detail headers, empty states, and agent ledgers.
• Show each connected server's Tycho version in Settings, and flag peers whose
  version differs from the host while keeping older peers backward-compatible as
  version unknown.

Other changes

• Prepare for a future GitHub App workflow, including device login,
  installation guidance, guarded review posting, immutable diff snapshots, and a
  paused Review Inbox while eager aggregation is redesigned. The GitHub App is
  not applicable for general use yet.
• Compact grouped Agents and Projects lists while preserving ownership,
  filtering, bulk archive behavior, and mobile action geometry.
• Add Claude Opus 5 to Claude model suggestions.
• Track lifetime agent run counts and preserve managed-agent run log offsets
  beyond the raw-log tail window.
• Add shared confirmation flows, contextual menu behavior, and composite
  Settings section patterns.

Fixes

• Make remote server tests independent of auth state.
• Preserve Now context menus across polling refreshes.
• Prevent schedule action menus from clipping.
• Stop agents with stale unstructured output and preserve stopped-agent signal
  exit status.
• Normalize GitHub CLI output as UTF-8.
