Windows RDP Keep Alive - Extend workspace sessions during active RDP connections #200
Description
The existing activity bump system activitybump.go only tracks certain connection types (SSH, VSCode, JetBrains, reconnecting PTY) workspaceagentstats.sql but doesn't include RDP connections in the activity detection.
Proposed Solution
Automatically extend workspace session timeouts when an active RDP connection is detected, similar to how SSH connections currently work.
Expected Behavior:
- Workspace remains active while RDP session is connected
- Session timeout resumes normal countdown after RDP disconnection
- No manual intervention required from users
Use Case: Windows development workspaces where users connect via RDP for GUI applications, Visual Studio, etc.
