v0.8.4

What's New

• Reaction auth fix — Mattermost reaction-based approvals (thumbsup/thumbsdown) now work with username-based allowlists (#98)
  • Resolves username from user ID via API with 5-minute TTL cache
  • Adds .catch() on async reaction handler to prevent unhandled rejections
• /reasoning applies immediately — no longer requires /new (#99)
  • Reloads session to apply new reasoning effort, preserving conversation context
  • Graceful fallback if session is stale or reload fails
