Fix response confirmation position and reduce thread wait time

[shima004]

This pull request includes a version bump for the adf_core_python package and minor improvements to connection handling and thread startup timing. The main changes are focused on improving the responsiveness of thread initialization and ensuring proper ordering in connection acknowledgment.

Core logic improvements:

• Moved the call to send_acknowledge after post_connect in handle_connect_ok to ensure that the acknowledgment is sent only after post-connection actions complete.

Threading and performance:

• Reduced the wait time for thread startup from 5 seconds to 1 second in start_connector_threads, which should improve startup responsiveness.

Versioning:

• Bumped the package version from 0.2.12 to 0.2.13 in pyproject.toml.
