DSH Im Gateway

Key features

• Harmonized gateway services — one plugin, three corridors.
• Tool approval bridge - angent calls the tool that requires authorization, a direct reply to "authorization" or "denial" in IM allows release/stopping, and overtime automatically delegates back to the dsh original approval system.
• The list of sessions and continuation - /sessions lists the most recent meetings (with headings),/continue resumes the given session.
• Plugin does not have any logs - Cordis defaults ctx.logger.
• All corridors are brought together into a single ctx.imGateway core: session management, slash commands, streaming responses, state broadcasting.
