v0.10.3

[0.10.3] - 2026-07-23

Fixed

• Trusted the official A3S tap before release smoke installation so current
  Homebrew versions can resolve the tap-owned a3s-webview dependency.
• Updated Core so the managed SRT capability handshake tolerates files and
  directories removed concurrently by other workspace processes.
• Included the complete causal error chain in local-sandbox startup warnings
  instead of hiding the actionable workspace or platform failure.
