feat: add --yes flag for auto-confirmation across multiple workflows

- Enhanced lite-execute, lite-fix, lite-lite-lite, lite-plan, multi-cli-plan, plan, replan, session complete, session solidify, and various UI design commands to support a --yes or -y flag for skipping user confirmations and auto-selecting defaults.
- Updated argument hints and examples to reflect new auto mode functionality.
- Implemented auto mode defaults for confirmation, execution methods, and code review options.
- Improved error handling and validation in command parsing and execution processes.

 **Resume Mode**: When called with `--resume-session` flag, skips discovery phase and directly enters TodoWrite generation and agent execution for the specified session.
 
+## Usage
+
+```bash
+# Interactive mode (with confirmations)
+/workflow:execute
+/workflow:execute --resume-session="WFS-auth"
+
+# Auto mode (skip confirmations, use defaults)
+/workflow:execute --yes
+/workflow:execute -y
+/workflow:execute -y --resume-session="WFS-auth"
+```
+
+## Auto Mode Defaults
+
+When `--yes` or `-y` flag is used:
+- **Session Selection**: Automatically selects the first (most recent) active session
+- **Completion Choice**: Automatically completes session (runs `/workflow:session:complete --yes`)
+
+**Flag Parsing**:
+```javascript
+const autoYes = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')
+```
