AttributeError: 'Connection' object has no attribute 'ssl' in sha256_password auth branch

[shychee]

Bug Description

In asyncmy/connection.pyx, the _request_authentication method still references self.ssl in the sha256_password branch (line 825), but PR #102 renamed self.ssl to self._ssl_context everywhere else.

This causes an AttributeError when connecting to a MySQL-compatible database that uses sha256_password authentication plugin.

How to Reproduce

1. Connect to a MySQL-compatible database (e.g. Huawei GaussDB) that uses sha256_password as the default auth plugin
2. Do not use SSL (ssl=None)
3. The connection fails with:

AttributeError: 'Connection' object has no attribute 'ssl'

Root Cause

PR #102 renamed self.ssl to self._ssl_context in __init__ and most of _request_authentication, but missed one reference in the sha256_password branch:

# connection.pyx line 825 (current, buggy)
if self.ssl and self.server_capabilities & SSL:

Should be:

# fix
if self._ssl_context and self.server_capabilities & SSL:
