feat: only warn about missing feature context fields when feature is used

- Added `noUncheckedIndexedAccess` option to `tsconfig.json` for stricter type checking.
- Modified `getFeatureDefinitions` method to now return synchronous`FeatureDefinition[]`.
- Enhanced error handling in `_getFeaturesRemote` method (no longer returns undefined, bug).
- Updated tests to reflect changes in feature handling and context warnings.
