fix(ci): disable compare-releases to unblock releases (#361)

The concurrency group fix was insufficient — the runner SIGTERM occurs
even with a single CI run. The compare-releases.py script itself causes
the runner to die (~86s, exit 143) regardless of concurrency. Disabling
the step entirely until the script is debugged in claude-desktop-versions.

The fallback notes and if: always() hardening remain in place.
