…eractionSupport Introduce the compiler SPI for routing mock interactions (and mock creation) through an owning Specification located outside the spec, plus the first mechanism that uses it: the `MockInteractionSupport` interface. A class implementing `spock.mock.MockInteractionSupport` supplies the owning spec through `getSpecification()`; its methods may then declare interactions and create mocks exactly as inside a spec. `SpockTransform` rewrites each declared method in place, routing creation/interactions through `getSpecification()`. A class cannot be both a `Specification` and a `MockInteractionSupport`. Rewritten methods are guarded with `Checks.notNull` so a missing (unattached) spec fails fast with a clear error. Foundation included here: - Spec-locator seam: `IRewriteResources.getSpecificationReference()` and `SpecialMethodCall.expand(Expression)`, consumed by `DeepBlockRewriter`, `SpecRewriter`, and `DefaultConditionRewriterResources`. - `MockingApi` converted from a class to an interface (with default methods) so non-spec types can mix in the factory methods; `Specification implements MockingApi`; `ClosureParameterTypeFromVariableType` accepts interface implementors. - External-rewriter infra: `ExternalRewriteResources`, `ExternalInteractionRewriter`, `ExternalInteractionMethod`, and the `Checks.notNull(T, String)` overload. Tests cover the seam, the MockingApi interface conversion, the closure-param path, the external rewrite resources, and MockInteractionSupport behaviour (cardinality, stubbing, mock creation, null-spec guard, static-scope error, both-spec-and-support error), plus an AST snapshot of the rewritten output.

Introduce the compiler SPI for routing mock interactions (and mock creation)
through an owning Specification located outside the spec, plus the first
mechanism that uses it: the
MockInteractionSupportinterface.A class implementing
spock.mock.MockInteractionSupportsupplies the owningspec through
getSpecification(); its methods may then declare interactionsand create mocks exactly as inside a spec.
SpockTransformrewrites eachdeclared method in place, routing creation/interactions through
getSpecification(). A class cannot be both aSpecificationand aMockInteractionSupport. Rewritten methods are guarded withChecks.notNullso a missing (unattached) spec fails fast with a clear error.

path, the external rewrite resources, and MockInteractionSupport behaviour
(cardinality, stubbing, mock creation, null-spec guard, static-scope error,
