chore: add buildOutput RTK filter, drop legacy cloud sync, internal cleanup

- feat(rtk): buildOutput filter + autodetect for npm/yarn/cargo logs
- chore: remove unused cloud sync module and related routes
- ui: hide deprecated providers (qwen, iflow, antigravity)
- chore: minor tray/cli/internal adjustments
