Resolve raw plugin config environment references before plugin discovery and validation, while preserving the existing single-pass behavior for configs already loaded through config IO.
The loader now resolves raw config opt-ins with config.env vars included, bypasses active/cache reuse for that mode, and redacts plugin entry config from raw-mode cache keys so resolved secrets do not enter registry keys or reentry errors.
