Implement C++ daemon with CMake, Ninja build system

Created complete C++ implementation:
- Core library (client, errors, capabilities)
- Query engine (AST, builder, normalizer)
- Utilities (UUID generation, exponential backoff)
- SQLite adapter and connection pool
- Daemon server with security manager
- Unit, integration, and conformance tests

Build system:
- CMakeLists.txt with optional Conan dependencies
- Renamed build assistant to .cjs for ES module compatibility
- Fixed conanfile.txt format for Conan 2.x
- All tests passing, daemon runs successfully
