Streamlines release workflow with static dev tag

Changes release artifact naming to use consistent 'latest' naming instead of date-based versioning. Implements cleanup of previous dev releases before creating new ones.

Benefits:
- Simplifies release artifact management
- Ensures only one development release exists at a time
- Maintains date information in release title for tracking
