feat: integrate driver and rename to ProposalDriver

- Wire ProposalDriver into the evaluation pipeline: add "subprocess"
to SUPPORTED_AGENT_TYPES, move SubprocessAgentConfig to core/models,
register in AgentDriverRegistry via new registry module, and update
all exports. Fixes ProposalDriver.__init__ to accept enabled kwarg.
- Extend unit tests
- Add agentic integration tests
