fix(env-loader): prevent dotenv override and preserve runtime/test variables

Ensure EnvironmentLoader no longer overrides existing $_ENV / putenv values.
Added pre-load snapshot + post-load restore mechanism to protect local,
CI, and PHPUnit variables from unexpected .env overwrites.
Improves reliability across libraries and guarantees test isolation.
