feat(agent): add command config to hermes/cursor agents + explicit env inheritance

- HermesAgentConfig.command: override hermes CLI path (default: "hermes")
- CursorAgentConfig.command: override cursor-agent CLI path (default: "cursor-agent")
- spawnCli: explicit env: process.env for clarity and future extensibility
- bundle-entry: read WORKFLOW_CURSOR_COMMAND from env
