Change streaming to use SignedTextAsRegularText instead of SkipSignedText. Signatures are tracked via last_signature and attached to function calls through effective_signature = signature.or(last_signature). Gemini 2.5 models include thoughtSignature on the first streaming chunk regardless of whether function calls follow. The old SkipSignedText behavior discarded text parts with signatures, causing content loss. Signature placement by model: - Gemini 2.5: first part (with or without function calls) - Gemini 3 with function calls: first function call part - Gemini 3 without function calls: last part if thought generated Signed-off-by: rabi <ramishra@redhat.com>

@jamadeo Hey! PTAL. This would fix a unique behavior of Gemini 2.5 models. |

Gemini 2.5 models include thoughtSignature on the first streaming chunk regardless of whether function calls follow. The old SkipSignedText behavior discarded text parts with signatures, causing content loss.
