feat: Implement council brief processing loop for task execution

Add processBriefs() polling loop that checks for assigned council briefs
and executes them using the ExecutionEngine infrastructure.

Changes:
- Add GetCurrentAssignment() public method to council.Manager
- Make HTTPServer.CouncilManager public for brief access
- Add processBriefs() 15-second polling loop in agent_support.go
- Add executeBrief() to initialize and run ExecutionEngine
- Add buildExecutionRequest() to convert briefs to execution requests
- Add uploadResults() to send completed work to WHOOSH
- Wire processBriefs() into StartAgentMode() as background goroutine

This addresses the root cause of task execution not happening: briefs
were being stored but never polled or executed. The execution
infrastructure (ExecutionEngine, AI providers, prompt system) was
complete but not connected to the council workflow.
