Adds update-major-tag.yml that triggers on any published release and
force-updates the major version tag (e.g., v6) to point to the latest
release (e.g., v6.0.1). Enables users to pin to @v6 instead of full
version numbers.

Remove the outdated rsyncwrapper dependency (unmaintained, uses
deprecated util._extend) and replace with a built-in buildRsyncCommand()
+ spawn implementation. Zero runtime dependencies.
BREAKING CHANGE: rsyncwrapper dependency removed, rsync command is now
constructed and executed directly via child_process.spawn.
