* feat: cpp-generator consumes logos-lidl; delete embedded frontend

The canonical LIDL frontend now lives in logos-lidl. cpp-generator links it
and keeps only the C++/Qt-specific parts (impl-header parsing, the gen_client/
gen_cdylib backends, the Qt type-name mapping).

- Delete the embedded lidl_lexer/parser/serializer/validator/ast.
- Add experimental/lidl_compat.h: brings logos-lidl's std AST into the global
  scope the backends use (via `using`), a qs() std::string→QString helper, a
  QTextStream<<std::string overload, and name-compatible shims (lidlParse/
  lidlSerialize/lidlValidate) so the emission code keeps compiling.
- Re-point impl_header_parser, lidl_gen_client (+ Doxygen /// docs on the
  generated client methods), lidl_gen_cdylib, lidl_emit_common, and legacy/
  main at lidl::ModuleDecl.
- CMake: C++17 + find_package(logos-lidl) + link logos-lidl::logos_lidl.
- bin.nix: distribute only the shared C++/Qt backend helpers (compat +
  impl_header_parser + emit_common) under share/lidl-frontend, not the frontend.
- tests: drop the 4 frontend test files (covered by logos-lidl now); the
  backend tests link logos-lidl.

* fix: pin logos-lidl to the C-ABI commit + lock it

The logos-lidl input was declared in flake.nix but missing from flake.lock,
so override chains that don't reach the nested input (the doctest harness
building a scaffolded module) couldn't resolve it. Pin the branch rev and
lock it so the component is self-contained. Re-point at master once logos-lidl
lands.
