v2.0 - candidate

[Seddryck]

Summary

• replace the embedded Sprache parser with the published Expressif.Syntax 0.10.0 package
• add a single Expressif.Bindings translation layer for syntax nodes and runtime semantic models
• migrate runtime, CLI, serializers, builders, and retained tests to the new boundary
• remove Expressif/Parsers and the Sprache dependency

This is an intentional next-major migration checkpoint. Existing tests remain active to show which legacy language behaviors are and are not represented by the current syntax package and binder.

Validation

• dotnet build Expressif.sln --no-restore --nologo -clp:ErrorsOnly — succeeded with 0 errors
• runtime tests (net10.0) — 2,651 passed, 215 failed, 1 skipped (2,867 total)
• CLI tests — 68 passed, 24 failed (92 total)
• no remaining NotImplementedException, Expressif.Parsers, or Sprache references

Known runtime failure groups: 144 syntax rejections, 30 unsupported intervals, 10 record-access binding gaps, 5 NuGet syntax-tree binding gaps, 5 other binding gaps, 20 other runtime errors, and 1 assertion mismatch. Native Tree-sitter loading succeeds.

Close #572
