fix: Make ACTIVATE and FORCE_PUSH flags explicit booleans

fix: Make ACTIVATE and FORCE_PUSH flags explicit booleans The `ACTIVATE` and `FORCE_PUSH` environment variables are now explicitly checked for a value of true (or false for `FORCE_PUSH`) to determine whether the corresponding command-line options are added. This makes the behavior more predictable and less susceptible to unexpected truthiness of non-empty strings.
