refactor: migrate log→tracing, add editor console/project, update CI

- Migrate entire workspace from log/env_logger to tracing/tracing-subscriber
- Rewrite EditorLogger as tracing_subscriber::Layer with MessageVisitor
- Add console panel with level filtering for editor GUI
- Add project management (create/open/save/import assets)
- Add cargo fmt check to CI workflow
- Update AGENTS.md dependencies and conventions
