Starts a new deployment for the specified config. Returns a task ID that can be
used to monitor deployment progress with `get_deployment_status`.

**Parameters:**
- config_id: The deployment config ID (get from list_deployment_configs or create_deployment_config)
- commit_sha: Optional specific commit to deploy (defaults to latest on branch)

**Prerequisites:**
- User must be authenticated via `sync-ctl auth login`
- A deployment config must exist (use create_deployment_config first if needed)

**Use Cases:**
- Deploy the latest code from a branch
- Deploy a specific commit version
- Trigger a manual deployment for a service

**Returns:**
- task_id: Use this to check deployment progress with get_deployment_status
- status: Initial deployment status
- message: Human-readable status message"#
