Fix CVE(s): CVE-2026-0864
* SECURITY UPDATE: configuration file injection via carriage returns in multi-line ConfigParser values (CVE-2026-0864) - debian/patches/CVE-2026-0864.patch: normalize CR and CRLF to LF plus tab continuation at both value-serialisation sites in RawConfigParser.write() in Lib/ConfigParser.py, so a carriage return inside an attacker-controlled value can no longer inject extra keys and sections into the written file; adds the upstream regression test to Lib/test/test_cfgparser.py. - CVE-2026-0864
