## 0.10.0

### Added

- `Parapet.Integration` behaviour (`@callback setup/0`) declared on all eight ecosystem integration
  adapters (Sigra, Accrue, Threadline, Chimeway, Mailglass, Rindle, Scoria, Rulestead). A missing
  or mis-named `setup/0` on any adapter is now a compile-time warning instead of a runtime
  `UndefinedFunctionError`.

### Fixed

- `Parapet.attach(adapters: [:rulestead])` no longer raises `UndefinedFunctionError`. The Rulestead
  adapter now exposes `setup/0` (delegating to `attach/0`), so all built-in integrations activate
  via the same `Parapet.attach/1` line.
