Stretch Goal: Interactive MAS Builder

[MonRos3]

Visual DAG builder that allows users to design a multi-agent system graphically and export it as a valid AETHER YAML config — no manual YAML editing required. Complements the YAML editor (Task 28) by targeting users who prefer a GUI-first workflow.

Definition of Done:

• "Builder" nav item accessible from navigation system; canvas allows adding agent nodes with configurable agent_id, role, objective, model_name, temperature, and max_tokens
• directed edges between nodes define channels with configurable protocol (direct/broadcast)
• workflow type inferred from graph topology or selectable via dropdown
• "Export YAML" button serializes the graph to a valid AETHER YAML config and offers it as a download
• "Send to Chat" and "Send to Visualizer" buttons load the built config directly into the corresponding page
• basic validation prevents export of invalid configurations (e.g. disconnected nodes, missing required fields)

Estimate: 21 points

Paraphrasing from @MonRos3 in slack conversation:

This is in the AETHER Stretch Goals epic, which will outlive the thesis. These are things that Dr. Pittman and I want to do sometime, but not before finishing the thesis. Maybe another student will take it on. Or maybe I can do it after graduating [unpaid]. But it's there for later.

Some of the components described in the ticket maybe complete, but the function of being able to build a directed acyclic graph [DAG] in the visualizer and then use that to export a config file and/or send it to chat to interact with are the main pieces. If it needs to be updated we can look at it, but it should stay since the main goal is the interactive, build a DAG and use it as a MAS component.

Keeping in the icebox for now. This will likely need to be broken down and rescoped - since this is living outside the main thesis work now, it's no longer a stretch goal in my eyes, it becomes just work in a post thesis epic.
