refactor godot-optimizer to use HTTP-based asset-server

Replace subprocess-based Godot execution with HTTP calls to
godot-explorer asset-server. Key changes:

- Add asset-server adapter for /process, /process-scene, /status APIs
- Simplify godot-optimizer to use asset-server for all processing
- Support scene (individual ZIPs), wearable, and emote entity types
- Add parallel profile processing with --profile option
- Remove old Godot project files and subprocess runner code
- Use quay.io/decentraland/godot-explorer:next as base image
