pub fn load_mlstack_env() -> boolExpand description
Load the .mlstack_env file into the current process environment.
Equivalent to source ~/.mlstack_env in the shell scripts.
Returns true if the file was loaded successfully.
Handles both direct exports (export VAR=value) and if-guarded exports
(if [ -z "${VAR:-}" ]; then export VAR=value; fi). Shell suffixes are
stripped to prevent ; fi from appearing in environment variable values.
