feat(enhanced): add request pattern filtering support for shared modules

- Add request filtering for direct matches in ConsumeSharedPlugin
- Add request filtering for resolved consumes in ConsumeSharedPlugin
- Add request filtering for direct matches in ProvideSharedPlugin
- Extend provide-filters integration tests with request pattern filtering
- Add comprehensive unit tests for filtering utilities

This implements PR5 from the incremental PR plan: Request Pattern Filtering
- Enables include/exclude.request filtering for shared modules
- Builds on existing filtering infrastructure from PR4
- Supports both string and RegExp request patterns
