v0.1.6

v0.1.6 — Microsoft Edge support

* Per-browser user records: `(email, browser_kind)` is the new identity
  key. Edge and Chromium with the same email are independent users.
* Edge support: empty IMPLICIT Nigori (MSA-keyed client init), 5
  permanent bookmark folders including `workspace_bookmarks`,
  `Diagnostic.SendCheckResult()` MSA private endpoint stub.
* Edge limitation: Edge does not send the account email — all Edge
  users converge to a single shared `anonymous@localhost` record.
  Multi-Edge-user setups need one selfsync instance per user.
* Schema migrations via sea-orm-migration. v0.1.5 databases
  auto-upgrade on startup (no manual db deletion required).
* Removed: `--relay-upstream` mode and the `edge.microsoft.com`
  fallback passthrough (and the reqwest/flate2/bytes deps).
