- add isync to setup.sh
- ask for gmail address alongside app password in integrations
- add PermanentError to job queue (skips retries for non-recoverable failures)
- use PermanentError for missing credentials, missing executable, auth failures
- auto-add /email to dock after successful gmail sync
- invalidate dock cache on sync completion for seamless UI update
