Currently input_schema must be a static array at registration time.

Request: Allow input_schema to be a callable that returns the schema, enabling context-aware parameters.

Use case: Automation pipelines where tool parameters depend on data collected earlier in the workflow. Parameters should exclude fields that already have values from previous steps.

wp_register_ability('myplugin/process-data', [
      'input_schema' => function(array $context): array {
          return MyPlugin\Schema::generate($context);
      },
  ]);
