Summary

• Adds an appliedDirectives: [__AppliedDirective!]! field to the __Directive introspection type, gated behind the EnableDirectiveIntrospection schema option, so directives applied to a directive definition become introspectable.
• Mirrors the existing appliedDirectives implementations on __Type, __Field, and __Schema. Stays out of standard introspection because __AppliedDirective is a non-spec Hot Chocolate extension.

Test plan

• New IntrospectionTests.AppliedDirectivesOnDirectiveDefinitionAreExposed: a directive definition carrying an applied directive round-trips through __schema { directives { appliedDirectives { name args { name value } } } }.
• Full IntrospectionTests suite green (net10.0); regenerated the four directive-introspection snapshots that enumerate every type's fields.

Pull request overview

This PR extends Hot Chocolate’s (non-spec) directive introspection support by adding appliedDirectives: [__AppliedDirective!]! to the __Directive introspection type, gated behind EnableDirectiveIntrospection, so directives applied to directive definitions can be introspected consistently with __Type, __Field, and __Schema.

Changes:

• Added appliedDirectives field to __Directive when EnableDirectiveIntrospection is enabled, resolving to the directive definition’s applied directives.
• Added a new regression test asserting applied directives on directive definitions round-trip through __schema { directives { appliedDirectives ... } }.
• Updated directive-introspection snapshots to account for the new __Directive.appliedDirectives field (and added a new snapshot for the new test).
