forked from unom/punktfunk
Every headless call went through `flatpak run io.unom.Punktfunk`, and the launch wrapper exec'd the same. On a Deck whose client came from a sysext, a .deb/rpm, an AUR build or a nix profile there is no such app: discovery worked (it is mDNS), and everything that needed the client — pairing, the library fetch, the host store, the stream launch itself — failed. Resolve the client once. The flatpak still wins when it is actually installed, so an existing Deck is byte-for-byte unchanged, and a native `punktfunk-client` is the fallback; `PF_DECKY_CLIENT` forces one on a machine with both. Both kinds share ~/.config/punktfunk — the flatpak's sandbox HOME is the real home — so identity, known-hosts and settings need no divergence. The wrapper takes the resolved binary as PF_CLIENT_BIN and execs it in place of `flatpak run`; kill_stream sends a name-matched SIGTERM where there is no flatpak instance to kill; and the client-update check, which reads the flatpak's tracked remote, simply reports nothing for a native install, whose updates belong to whatever installed it. Installed-ness is now decided by the app's exported directory rather than by the presence of the `flatpak` binary, so a machine that has flatpak but not this app no longer resolves to a client that cannot run.
