Electron's main process set app.setName(...) but never overrode userData,
so Chromium runtime state (cache, cookies, local/session storage, crash
dumps) defaulted to ~/Library/Application Support/<name>. Older dev builds
also wrote the daemon DB there. Pin userData to ~/.ao/electron so the
entire app footprint lives under the canonical AO home alongside the
daemon data dir and running.json; sessionData and crashDumps derive from
userData, so the single override reparents them all.
Document the ~/.ao-only rule as a hard boundary in AGENTS.md and CLAUDE.md.
Closes#368
