Bug: Inconsistent Attachment Data Types

The attachments field has an inconsistent data type: user messages now store attachments as an array, while assistant messages still store them as a JSON string ('[]'). This type mismatch violates data consistency, causing potential runtime errors and data handling issues when processing messages. Existing tests confirm this discrepancy, expecting different types for user versus assistant message attachments.

	];
	if (! isset($parts[$chunk->chunkType->value])) {
	$parts[$chunk->chunkType->value] = '';
	}
	$parts[$chunk->chunkType->value] .= $chunk->text;
	yield json_encode($chunkData)."\n";

Bug: Concurrent Uploads Reset Flag Prematurely

The isUploading flag is prematurely reset to false when multiple files are uploaded concurrently, as it's cleared in the finally block of each individual upload, even if other uploads are still in progress. This leads to an inaccurate overall upload status. Furthermore, the uploadQueue removal logic using indexOf(file.name) is flawed; it can incorrectly remove or leave entries in the queue if multiple files with identical names are uploaded.
