// Step 1912: Sprint 276 Integration
// End-to-end: poly-sort project — goto-definition from a Python call site
// lands on the Rust sort-core provider via LSP proxy + cross-language resolver.
//
//  t1: PolySortProject symbols load into symbol table
//  t2: LSP textDocument/definition request routes through proxy
//  t3: CrossLanguageBoundaryDetector identifies sort_array as boundary
//  t4: CrossLanguageDefinitionResolver returns Rust provider location
//  t5: Sprint276IntegrationSummary reports complete
