Decompose AgentsHubView (785 lines) into smaller views

[2witstudios]

Problem

AgentsHubView.swift is 785 lines containing:

• The main AgentsHubView struct (~630 lines)
• AgentsHubTab enum
• CommandHintBar, PromptListRow, AgentListRow, SwarmListRow, SwarmDiagramView

The main struct has deeply nested computed properties:

• promptsContent alone is ~127 lines of nested view code with an inline prompt editor
• Three nearly identical list panels (promptListPanel, agentListPanel, swarmListPanel) that could be a generic ListPanel<Item, Row>
• Three list row types with identical selection card styling that should be a shared ViewModifier

Suggested approach

1. Extract promptsContent → PromptEditorView (own file)
2. Extract agentsContent → AgentDetailView (own file)
3. Extract swarmsContent → SwarmDetailView (own file)
4. Create a generic ListPanel<Item, Row> to replace the three identical list panel implementations (~60 lines saved)
5. Create a SelectableCardStyle ViewModifier for the repeated selection styling pattern:

   .padding(12)
   .frame(maxWidth: .infinity, alignment: .leading)
   .background(isSelected ? Color.accentColor.opacity(0.12) : Color.primary.opacity(0.03))
   .clipShape(RoundedRectangle(cornerRadius: 10))
