docs: update handover command documentation for clarity and accuracy

- Corrected the primary output location path to include a leading dot.
- Added critical instructions for obtaining timestamps programmatically.
- Enhanced implementation steps to emphasize timestamp usage and file saving to both primary and backup locations.
- Included verification step for date consistency between filename and document header.

+**CRITICAL**: Always obtain the timestamp programmatically:
+```bash
+# Generate timestamp - NEVER type dates manually
+TIMESTAMP=$(date +"%Y-%m-%d-%H-%M-%S")
+FILENAME="handover-${TIMESTAMP}.md"
+```

 ## Implementation
 
-1. Generate handover using `{{HOME_TOOL_DIR}}/templates/handover-template.md`
-2. Replace all `{{VARIABLE}}` placeholders with actual values
-3. Save to the specified location
-4. Display the full file path to the user for reference
+1. **ALWAYS** get the current timestamp using `date` command:
+   ```bash
+   date +"%Y-%m-%d %H:%M:%S"  # For document header
+   date +"%Y-%m-%d-%H-%M-%S"  # For filename
+   ```
+2. Generate handover using `~/.claude/templates/handover-template.md`
+3. Replace all `{{VARIABLE}}` placeholders with actual values
+4. Save to BOTH locations (primary and backup)
+5. Display the full file path to the user for reference
+6. Verify the date in the filename matches the date in the document header
 
 The handover document will be saved as a markdown file and can be used to seamlessly continue work in a new session.
