fix(chat): send temperature through modelOptions, where LLPhant reads it

[rubenvdlinde]

Four assignments of $config->temperature and one of $config->organizationId on LLPhant\OpenAIConfig. Neither is a property of that class, so each created a dynamic property that nothing ever read. An agent temperature configured in the UI never reached the model.

The suppressions sitting above them said as much, and had been read the wrong way round:

@psalm-suppress UndefinedPropertyAssignment LLPhant dynamic properties

LLPhant does not use dynamic properties. It reads modelOptions:

OpenAIChat.php:89   $this->modelOptions = $config->modelOptions;
OpenAIChat.php:368  $openAiArgs = $this->modelOptions;

and OpenAIConfigs own docblock lists temperature inside the ModelOptions array shape, not among its properties. Nothing in the library reads a temperature property anywhere. Temperature now goes to $config->modelOptions["temperature"], which is what actually reaches the API.

organizationId is removed rather than relocated: LLPhant has no organization support of any kind, so there is nowhere for it to go. That drops the pretence, not the behaviour, because there was none.

Worth noting PHP 8.2 deprecated dynamic property creation, so this was heading for deprecation notices and then hard failure regardless.

Verification

vendor/bin/psalm 5.26.1 on PHP 8.3: errors with the baseline emptied went 173 -> 168, regenerated baseline green. PHPUnit not run locally (needs the server bootstrap).
