v0.8.3

Added

• Anonymous install ping, folded into the existing update check
  (GET /api/updates) for free instead of an extra network call: a random
  per-install id plus your app version and OS family, so we know roughly how
  many installs exist. Never sends host, username, path, account info, or
  your IP. Opt out with DEVWEBUI_NO_PING=1 (the older
  DEVWEBUI_PULSE_DISABLE=1 / CONNECTIONS_PULSE_DISABLE=1 still work too);
  already off automatically in dev/test/CI. Full detail in the README's
  Local-first section.

Changed

• Retired the dormant pulse machinery (POST /api/pulse, the
  app_opened client ping) end to end. It only ever fired at
  DEVWEBUI_PULSE_URL, which nothing has ever set, so it was pure dead code
  now superseded by the install ping above. The install id itself survives:
  it reuses the existing pulseInstallId settings slot rather than minting
  a second one.
