(Migrated from github.com)

Foundation of the split PR stack (#12 → #13 → #14 → #15 are based on this branch). Three commits:

handler: optional working_dir — override the game process cwd for launcher-shim titles whose real binary lives in a subdir but must run with cwd higher up (e.g. native Frozenbyte titles).
launch: per-process concurrency — namespaced scratch (tmp/<launch_ns>) + per-launch window ownership so two concurrent splitux processes don't collide on scratch dirs or grab each other's gamescope windows.
audio + concurrency — per-instance virtual capture sinks (so each together stream taps only its own game's audio) + crash-safe orphan cleanup (pid-aware scratch reaping).

Merge this first; the four split/* PRs then stack on top in order.
