feat: add IsSet, AllKeys, AllSettings; fix env precedence for file-only keys

- collapse() now applies env vars for keys present in fileConfig, not
  just defaultConfig. Previously, env vars couldn't override file values
  unless a default was also set for that key.
- SetDefault no longer pollutes overrideConfig; it correctly resolves
  the value by checking override > env > file > default.
- Remove unused explicitDefaults field and UseExplicitDefaults method.
- Add IsSet, AllKeys, AllSettings methods + package-level wrappers.
- Add missing package-level wrappers: Get, SetBool, SetString,
  SetConfigDir, WithEnvPrefix.
- Add tests for all new methods and the env-over-file-without-default
  fix.
