* feat(lock): Add support for disabling lock manager Implement control of lock system activation and deactivation via environment variables Add DisabledLockManager for lock-free operation scenarios Introduce LockManager trait to uniformly manage different lock managers Signed-off-by: junxiang Mu <1948535941@qq.com> * refactor(lock): Optimize implementation of global lock manager and parsing of boolean environment variables Refactor the implementation of the global lock manager: wrap FastObjectLockManager with Arc and add the as_fast_lock_manager method Extract the boolean environment variable parsing logic into an independent function parse_bool_env_var Signed-off-by: junxiang Mu <1948535941@qq.com> --------- Signed-off-by: junxiang Mu <1948535941@qq.com>
