feat: add email deletion tools for AI-assisted inbox management
New Deletion Tools (4 total): - imap_delete_message: Delete single message with confirmation requirement - imap_delete_messages: Bulk delete multiple messages with confirmation - imap_move_to_trash: Safe delete by moving to Gmail Trash folder - imap_expunge_folder: Permanently remove deleted messages from folder Safety Features: - Confirmation prompts for all permanent deletions (confirmed: true required) - Move to trash as safe, reversible deletion option - Warning messages explaining consequences before action - Support for both single UID and bulk UIDs array operations AI Assistant Integration: - Perfect for AI-driven email cleanup workflows - "Delete promotional emails older than 6 months" use cases - Safe workflow: search โ†’ review โ†’ move to trash โ†’ confirm permanent - Bulk operations for efficient inbox management Technical Implementation: - IMAP STORE +FLAGS (\Deleted) + EXPUNGE for permanent deletion - IMAP MOVE command for Gmail Trash folder operations - Fallback to COPY + DELETE + EXPUNGE for non-MOVE servers - Thread-safe operations with proper channel handling Documentation Updates: - Updated README.md with 12 tools and new deletion features - Enhanced CLAUDE.md with AI-assisted email management section - Comprehensive help text with deletion examples and safety notes - Updated integration tests to verify all 12 tools Live Testing: - Successfully tested with Gmail account mo.khan@gmail.com - Moved 4 spam emails to trash safely and reversibly - Confirmed safety features and bulk operations work correctly - Verified tool count and functionality in integration tests ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

+### **๐Ÿค– AI-Assisted Email Management**
+
+**The IMAP MCP server now enables powerful AI-driven email cleanup and management:**
+
+**Safe Deletion Workflow:**
+1. **Search**: Use `imap_search_messages` to find emails matching criteria
+2. **Review**: Use `imap_read_message` to analyze specific emails  
+3. **Safe Delete**: Use `imap_move_to_trash` to move to Gmail Trash (reversible)
+4. **Permanent**: Use `imap_delete_message` with confirmation for permanent removal
+
+**AI Assistant Use Cases:**
+- *"Delete all promotional emails older than 6 months"*
+- *"Remove unread newsletters from last year"*
+- *"Clean up emails from specific senders"*
+- *"Delete emails matching certain subject patterns"*
+- *"Find and remove large attachments to free space"*
+
+**Safety Features:**
+- **Confirmation Required**: All permanent deletions require `confirmed: true`
+- **Trash by Default**: `imap_move_to_trash` for safe, reversible deletion
+- **Bulk Operations**: Handle multiple messages efficiently with UIDs array
+- **Warning Messages**: Clear warnings about permanent actions
+
+**Example AI Workflow:**
+```
+1. Search: "Find all emails from newsletters older than 1 year"
+2. Review: "Show me 5 examples of what would be deleted"
+3. Safe Delete: "Move these 150 newsletter emails to trash"
+4. Confirm: "If everything looks good, permanently delete from trash"
+```
+
 **Security Notes:**
 - Use app passwords for Gmail (not main account password)
 - Consider environment variables for credential management
 - All connections use TLS encryption by default
-- Credentials are not logged or stored persistently by the server
\ No newline at end of file
+- Credentials are not logged or stored persistently by the server
