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.

+## Auto Mode Defaults
+
+When `--yes` or `-y` flag is used:
+- **Categories to Clean**: Auto-selects `["Sessions"]` only (safest - only workflow sessions)
+- **Risk Level**: Auto-selects `"Low only"` (only low-risk items)
+- All confirmations skipped, proceeds directly to execution
+
+**Flag Parsing**:
+```javascript
+const autoYes = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')
+const dryRun = $ARGUMENTS.includes('--dry-run')
