LoxBerry MCP Server 0.4.0-alpha.13

• Stop the MCP service before an upgrade replaces its persistent auth data, so
  in-flight requests cannot fail against a temporarily unavailable store.
• Classify a Miniserver source-IP lockout received while sending a WebSocket
  command as a recoverable connection failure, including deferred token cleanup.
• Keep a failed Loxone binary-state stream fail-closed while recording only its
  sanitized exception class; the stream task is now consumed after that record
  so its error cannot be raised a second time during session cleanup.
• Restore Gen. 1 Loxone token authentication by using the firmware-supported
  JWT credential inside RSA/AES Command Encryption instead of the rejected
  token-hash variant; the independent Gen. 2 hash path remains unchanged.
• Stop Loxone token authentication attempts after three rejections of the
  authwithtoken step per OAuth session until a local administrator explicitly
  permits another bounded attempt. Miniserver source-IP lockouts are reported
  separately and never increment that counter.
• Enable LoxBerry Plugin Manager automatic update discovery for stable releases
  and explicitly opted-in prereleases.
