feat: cursor agent auto-extracts workspace from context via LLM

- workflow-agent-cursor: workspace config now optional (string | null)
- When null, uses LLM call to extract workspace path from AgentContext
  (previous steps' meta, start prompt) before spawning cursor-agent CLI
- Requires llmProvider when workspace is null
- develop bundle-entry: switched from hermes to cursor agent for all roles
- solve-issue bundle-entry: created, developer role uses workflowAsAgent('develop'),
  preparer/submitter remain hermes
