Add build modes and dev hooks, improve injection and docs

Introduces build mode options (rmfakecloud, qmldiff, dev, all) to CMake and build scripts, enabling selective compilation of hooks for cloud redirection, Qt resource hooking, and reverse engineering. Adds new hooks and memory logging for dev mode, updates injection script to handle libzstd.1.dylib dependency, and documents build modes in README.
