Agentlas OS 1.2.68

• Sign-in: auth status (CLI and the agentlas_auth_status MCP tool) renews a
  saved sign-in whose one-hour access token has aged out, instead of reporting
  the engine as signed out after an app update or restart. A refused grant
  reports sign_in_required, an unreachable server reports refresh_deferred,
  and an unreadable record says so; --no-refresh keeps the plain read.
• Local models: the OS judge's Ollama runner sizes the context window from the
  model's trained maximum and tells Ollama not to truncate, so long prompts are
  no longer silently cut on machines with a small default window. A prompt too
  large for the model stops with local_context_limit_exceeded.
• Windows: engine background jobs (update worker, runtime health checks, memory
  hook installer, detached memory worker and their children) no longer open
  blank console windows.
• Windows: the ontology reads its stored file:///C:/... and UNC source
  addresses back as the same files, so project verification and queries no
  longer report every source as deleted. Existing databases need no migration.
