v0.14.1

New Features

• Autumn balances.update — the Autumn emulator now supports the SDK's balance update call (POST /v1/balances.update) for reconciling continuous-use features such as seats. Exactly one of usage, remaining, or add_to_balance is required; the update is recorded as an adjustment event, so events.list shows the reconciliation and balances.check and customers.get_or_create reflect it from the same state. remaining is rejected on unlimited balances, unknown customers 404 with Autumn's real customer_not_found code (update is a non-creating endpoint upstream, unlike track and check), and a feature the customer's plan does not carry 404s.
