Summary

• complete completeness-gated workspace rename and the remaining semantic navigation domains
• add versioned snapshots, debounce/cancellation, cached analysis, reverse diagnostic invalidation, live diagnostics policy, and safe assembly reload
• add state-machine/debugger metadata, stable generated-code presentation, async stepping records, and debugger-compatible PDB document/path metadata
• add structured interop quick fixes in both LSP feature modes
• update editor/debugger status and standalone Neovim/Helix setup documentation

Advances #1306 through all remaining code priorities. The documented real-debugger smoke checklist remains an external validation item: both tested netcoredbg builds failed on a Roslyn-generated C# control program in this environment, while the portable-PDB metadata and compatibility regressions are covered automatically.

Validation

• dotnet test SharpTS.sln --no-restore --filter "Category!=LiveNetwork&Category!=LoadSensitive" (16,272 passed)
• dotnet test SharpTS.Test262/SharpTS.Test262.csproj --configuration Release --no-restore (186 passed, 4 diagnostic skips)
• dotnet test SharpTS.TypeScriptConformance/SharpTS.TypeScriptConformance.csproj --configuration Release --no-restore (45 passed)
• npm run compile in vscode-sharpts
• dotnet pack SharpTS.LanguageServer/SharpTS.LanguageServer.csproj --configuration Release --no-restore
• real LSP initialize handshakes advertise quickfix in both interop-only and full modes
