Text, Markdown and JSON readers accept streams with non-string names

Agno's readers build a document name from file.name, and a stream opened from a file descriptor, like os.fdopen(fd, "rb") on a tempfile.mkstemp() handle, reports an integer there. Earlier releases called .split(".") on it. TextReader and MarkdownReader logged the error and returned nothing, and JSONReader raised. All three now fall back to a default name.

Real output reading a descriptor-backed temporary file with each reader:

Before: TextReader     name 3 -> 0 docs []
        MarkdownReader name 4 -> 0 docs []
        JSONReader     -> AttributeError 'int' object has no attribute 'split'
 
Now:    TextReader     name 3 -> 1 docs ['text_file']
        MarkdownReader name 4 -> 1 docs ['file']
        JSONReader     name 3 -> 1 docs ['json_file']

The fix covers read() and async_read() on the text and Markdown readers. A name= argument still wins over the default.

See the cookbook, and learn more about readers, the Markdown reader and the JSON reader in the documentation.
