A major update that adds HTTP/HTTPS proxy support for the DuckDB Google Sheets extension via environment variables (HTTP_PROXY, HTTPS_PROXY, NO_PROXY). Changes: - Added 225+ lines implementing proxy support using HTTP CONNECT tunneling - New proxy configuration structure with username/password support - Environment variable parsing with NO_PROXY pattern matching - Low-level POSIX socket operations for manual TCP connections
Added C++17 standard requirement to CMakeLists.txt to fix compilation error with std::optional.
