v6.0.5

Added

• A public roadmap (#723). /resources/roadmap states where AgentDeck is going: reach across
  protocols through 6.x, programmable execution and debugging in v7, isolation and sandboxing in
  v8, and rooms, automation, batteries and operations as directions rather than a release order. No
  dates. Protocol sequencing stays authoritative in the repository's protocol roadmap.

Changed

• Ask Jack says he is away before you type, rather than after (#224). The docs site checks the
  assistant's /health on load: when it is unreachable the launcher reads "Jack is away" and takes
  no question, instead of accepting one and failing on send. A backend that answers with an error
  reads differently from one that is not running.
• The observability extra now requires Langfuse 4.x (#748). langfuse>=4.15.2 and
  openinference-instrumentation-openai-agents>=2.4.1, up from >=2.60 and >=0.1. Langfuse 4
  is past their OpenTelemetry rewrite, so an environment pinning Langfuse 2.x will not resolve
  agentdeck-sdk[observability] until it moves. AgentDeck's own observer surface is unchanged:
  Deck(observers=[Langfuse()]) is the same call and the same behavior.
