macOS disk full: Aside browser leaks mailq_* SQLite temp dirs

When a Mac running the Aside AI browser runs out of space, check ~/.aside/runtime/tmp first. Every agent run creates a mailq_<random>/ folder with a ~118 MB SQLite db (ei, ei-shm, ei-wal) and never removes it. In one audit there were 1,082 of them using 121 GB, 467 of them created on a single day. Session scratch under ~/.aside/u/<n>/sessions/*/tmp added another ~41 GB, while messages.jsonl in each session is the actual chat history. Quit Aside before deleting, keep the most recent folders, and expect them to come back unless a periodic cleanup job is set up. For general audits, du -sh -x per folder plus zsh glob caveats (an unmatched glob like .[!.]* aborts the whole command) saved time.
