Add possibility to add structured output for Chat action or create a separate action.

>>> [!note] Migrated issue   Reported by: [marcus_johansson](https://www.drupal.org/user/385947) Related to !4 >>> <h3 id="summary-problem-motivation">Problem/Motivation</h3> Structured Output is something that has gone a little bit in the shadows due to Function Calling being added in 1.1.0, but its actually quite powerful as well and a very good fit with ECA. I have added an issue here <a href="https://git.drupalcode.org/project/ai/-/work_items/3544533" class="drupalorg-gitlab-link">https://git.drupalcode.org/project/ai/-/work_items/3544533</a>, because I realized its not even documented, but what you can do with providers that support it is, adding something in the line of <pre>$schema = [   'name' => 'countries_population',   'schema' => [     'type' => 'object',     'properties' => [       'countries' => [         'type' => 'array',         'minItems' => 1,         'items' => [           'type' => 'object',           'properties' => [             'name' => ['type' => 'string', 'minLength' => 1],             'iso_code' => ['type' => 'string', 'pattern' => '^[A-Z]{2,3}$'],             'population' => ['type' => 'integer', 'minimum' => 0],             'year' => ['type' => 'integer', 'minimum' => 1800, 'maximum' => 2100],           ],           'required' => ['name', 'population'],           'additionalProperties' => false,         ],       ],     ],     'required' => ['countries'],     'additionalProperties' => false,   ], ]; $messages = [new ChatMessage("List the population of Germany, France and Spain")]; $input = new ChatInput("User", $messages); $input->setChatStructuredJsonSchema($schema);</pre>and it would return <pre>{   "countries": [     { "name": "France",  "iso_code": "FR", "population": 68600000, "year": 2025 },     { "name": "Germany", "iso_code": "DE", "population": 83600000, "year": 2025 },     { "name": "Spain",   "iso_code": "ES", "population": 49077984, "year": 2025 }   ] }</pre>Because ECA has the "Render: unserialize" action, it should be able to split up the result and do really complex things with this. <h3 id="summary-proposed-resolution">Proposed resolution</h3> Either add a new action specifically for structured output chat or add it as an option to the chat action.
