FastLogs 0.4.1

Fixed: built-in command names are all-lowercase (fastlogs.scenecontext); the server rejects uppercase command names, so the documented camelCase spelling could never be enqueued. Also ships the scoped COMMAND_TOKEN, the /api/v1 canonical alias and online backups (script + daily systemd timer). Install (Unity): add https://github.com/AitiX/Fastlogs.git?path=/unity#v0.4.1 to Packages/manifest.json.
