Refresh PR #2258 onto master at 5427cbcc19 so the session-log export fixes are evaluated and mergeable against the current repository.\n\nPreserve master's SDK-toolchain removal, client theme bootstrap, and Python finish-reason changes intact. The only textual overlap is the generated config-catalog pairing record: both English and Chinese catalogs merge cleanly with the PR's compression setting and master's package moves, so regenerate that sidecar from the merged owners instead of choosing either stale hash.
