fix: Add missing deployment_status and deployment_message columns to teams table

## Problem
WHOOSH was failing to update team deployment status with database errors:
- ERROR: column 'deployment_status' of relation 'teams' does not exist (SQLSTATE 42703)
- This prevented proper tracking of agent deployment progress

## Solution
- **Added migration 007**: Creates deployment_status and deployment_message columns
- **deployment_status VARCHAR(50)**: Tracks deployment state (pending/success/failed)
- **deployment_message TEXT**: Stores deployment error messages or status details
- **Added index**: For efficient deployment status queries
- **Backward compatibility**: Sets default values for existing teams

## Impact
- ✅ Fixes team deployment status tracking errors
- ✅ Enables proper agent deployment monitoring
- ✅ Maintains data consistency with existing teams
- ✅ Improves query performance with new index

This resolves the database errors that were preventing WHOOSH from tracking autonomous team deployment status.
