📡 Issue 11: Integrate XMPP Bot using Tigase XMPP Server

Description: Integrate Sztab with Tigase XMPP Server to enable chat-based project interaction:

• Create an XMPP bot user that can:
  • Respond to commands like /status, /create issue, /assign, etc.
  • Send real-time notifications (new issues, comments, etc.)
  • Participate in daily standups or nudges

Tasks:

•  Define XMPP bot user and register with Tigase
•  Add basic message parsing logic in Java bot
•  Enable:
  • /status → responds with open issues, overdue items
  • /create issue → parses and creates new issue
  • Push alerts on assignment or comment
•  Bridge bot actions to Sztab REST APIs
•  Deploy bot alongside backend (Docker)

Estimated Effort: 12–16 hours Milestone: Milestone 2 – Post-MVP
