            Log:
            [rebase 3/4] Add Python 3.15 SSL compatibility patch

Guard 'ssl.PROTOCOL_TLSv1', 'ssl.PROTOCOL_TLSv1_1', and
'ssl.PROTOCOL_TLSv1_2' with hasattr() checks in three files:
'network.py', 'aio/network.py', and 'connection.py'.

Python 3.15 (PEP 644) removed these legacy TLS protocol constants.
Without this patch, any code path touching TLS version selection
raises AttributeError on Python 3.15+.

+# Fix Python 3.15 SSL/TLS compatibility
+#
+# Python 3.15 removed the deprecated ssl.PROTOCOL_TLSv1, ssl.PROTOCOL_TLSv1_1,
+# and ssl.PROTOCOL_TLSv1_2 constants (PEP 644). The hardcoded dictionary
+# construction raises AttributeError on Python 3.15+.
+#
+# Replace direct references with hasattr() guards so only the constants
+# available on the running Python version are registered. TLS 1.0 and 1.1
+# are obsolete anyway — the main functional protocol is TLSv1.3 via
+# ssl.PROTOCOL_TLS.
