Improve test coverage for provider implementation#182
Conversation
Implement give_me_vertices provider algorithm that returns toy::VertexCollection struct instead of fundamental type. Wire stub provider into framework_graph with unlimited concurrency. Update VertexCollection::data to use std::size_t.
- Add provide() member to glue class for provider registration - Document glue class template with comprehensive description of its role in flow graph registration - Document make_glue() helper explaining void_tag behavior and state management - Update provider_test to use provide() instead of provider() for consistency with other node types
Introduce declared_provider class and provider_node template for handling data input into the graph. Providers accept level_id and generate products. Add provider registration to node_catalog and glue interface. Register providers using input_family syntax for consistent product association. Update provider_test to use level_id reference and specified_label syntax for provider registration.
Add provider_node template class that creates data products on-demand from level IDs. Providers are registered via the provide() API and wired into the graph by edge_maker, which matches provider outputs to consumer inputs based on product labels and families. Modify multiplexer to route messages to provider nodes based on level information. Update node_catalog to track provider execution counts. Add provider_test.cpp demonstrating provider registration and execution with a toy VertexCollection example. This development is not yet complete. All the libraries compile and link, and all the tests compile and link. But most tests that use a graph fail, because they have not yet been updated to include the providers needed to work with this version of the infrastructure.

Pull request overview
This PR improves test coverage for the provider node implementation by adding a test case that exercises the flush message handling code path in declared_provider.hpp (lines 75-77). The test verifies that flush messages pass through providers without incrementing execution counts, ensuring that the framework correctly distinguishes between regular data processing and flush signals.
Key Changes
- Added
provider_with_flushtest case that sends flush messages after each spill-level data cell - Test confirms flush messages are handled without triggering provider execution
