[1.57.3] - 2026-08-02

Fixed

• Cross-process outcome reporting: pending outcomes now persist to SQLite
  (pending_outcomes table, schema v5) so vaara outcome works when called
  from a separate process than vaara check.
• macOS AccessibilityObserver rewrite: proper multi-app focus tracking via
  NSWorkspace notifications, correct Safari URL extraction through toolbar
  AX hierarchy, broader AI site detection, and cleanup of stale observers.
• Remove accidentally committed temporary release artifacts
  (.commit_msg_v1.53.0_release.txt, .pr_body_v1.53.0.md).
