Replace the direct agent config dialog with a choice modal offering two
paths: "Ask the CEO to create a new agent" (opens pre-filled issue) or
"I want advanced configuration myself" (navigates to /agents/new).
- Extend NewIssueDefaults with title/description for pre-fill support
- Add /agents/new route with full-page agent configuration form
- NewAgentDialog now shows CEO recommendation modal
