# Description

This PR adds a convenience method for constructing a Client from either
an AgentCard URL or an AgentCard directly. The goal is to reduce the
number of lines of code required for simple client creation, but still
enabling more advanced handled of client construction.

Usage example:

```python
my_agent_url =  'https://travel-agent.example.com'
client = await ClientFactory.connect(my_agent_url)
await client.send_message(...)
```

… be larger size (10mb) (#518)

# Description
The current max content length for file attachment in an A2A request is
only 1mb which is too small for most files. Change MAX_CONTENT_LENGTH to
be larger size (10mb). (Note currently we only have this limit for
json-rpc)

# Description

This pull request refactors utility functions for handling `Part`
objects by moving them from `src/a2a/utils/message.py` to a new
dedicated module `src/a2a/utils/parts.py`. It also introduces a new
helper function for extracting text from `Artifacts` and updates imports
and exports to reflect these changes. The goal is to improve code
organization and clarity by grouping similar functionality.

**Refactoring and organization:**

* Moved the functions `get_text_parts`, `get_data_parts`, and
`get_file_parts` from `src/a2a/utils/message.py` into a new module
`src/a2a/utils/parts.py`, providing better separation of concerns for
part-handling utilities.

* Updated imports in `src/a2a/utils/__init__.py` to re-export these
part-handling functions from the new `parts` module, and removed their
previous import from the `message` module.

**New functionality:**

* Added the new function `get_artifact_text` to
`src/a2a/utils/artifact.py` for extracting and joining all text content
from an artifact's parts, using the refactored `get_text_parts`.

These changes improve maintainability by clearly separating
message-related and part-related utilities, and by introducing a helper
for artifact text extraction.
