build_all: incremental build + per-step toolchain install

Skip steps whose dist/ artifact already exists; add --clean/-c to
force a full rebuild. Install sphinx/linuxdoc, build, pyinstaller
in their respective steps instead of upfront. Auto-add flathub
remote and install missing Flatpak SDK/runtime deps before step 4.
