RoyalDownloader v1.0.0-rc.2

RoyalDownloader v1.0.0-rc.2

v1.0.0-rc.2 is the second release candidate. It introduces the persistent
two-channel updater model while preserving existing HTTP, /api/v1, WebSocket,
Docker, persistence, update, backup, and rollback contracts.

Highlights

• Stable remains the backward-compatible default and follows main only.
• Overnight follows the separate overnight branch and is clearly marked as a
  potentially unstable development channel.
• Channel selection persists across application and container restarts.
• Returning to an older or diverged Stable state requires explicit
  confirmation and uses the existing backup and rollback path.
• Overnight commits are offered only after the complete Quality workflow has
  succeeded for the exact revision.
• Application version, selected channel, source branch, installed commit, and
  available commit remain separately visible.
• Release publication now marks semantic pre-release versions such as this RC
  as pre-releases without forcing future stable versions into that state.

This remains a release candidate. Back up data/ and runtime/ before an
upgrade. External providers may change their pages, domains, availability, or
protection mechanisms independently of RoyalDownloader.
