Installs the full apt dependency set for a clean Ubuntu 26.04 machine (build toolchain, Qt 6, libcurl/sqlite/openssl/secret, ffmpeg, node, lint tools), then verifies versions: cmake >= 3.28, g++ with working -std=c++23 <expected>, node >= 20, and every -dev package via pkg-config. --with-clang adds LLVM for the M7 fuzz targets; --packaging adds .deb tooling; --check verifies without installing. Flags the CMake 4.x pre-3.5 cmake_minimum_required hazard from the brief. Co-Authored-By: Claude Sonnet 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HPPSGhiArbvQgwC2DNiURS
