Subject: [PATCH] fix(cli): allow mutable install for monorepo yarn.lock
 (#2408)

This change updates the CLI to use `--no-immutable` when a plugin package or
monorepo `yarn.lock` file is used during the `export-dynamic-plugin` command.
Explicitly passing this flag avoids the default Yarn 3.x behavior of
`--immutable` when the command is run in a CI environment.
