Two fixes from live Bazzite testing of the managed-Gaming + mid-stream work:
1. Input now FOLLOWS the active session. The host-lifetime injector was pinned to
the first backend it opened and only reopened on an inject FAILURE — but with
Feature A keeping the managed gamescope warm, its EIS socket stays alive, so a
switch to the KDE desktop + reconnect kept injecting into the idle gamescope
(input silently dead on KDE). injector_service_thread now compares the
resolved input backend (default_backend() ← PUNKTFUNK_INPUT_BACKEND, set per
connect by apply_input_env, and on a mid-stream switch) each event and reopens
when it changes. Fixes input on a Gaming->Desktop reconnect AND Feature B's
mid-stream input re-route, with no plumbing.
2. Debounced TV-restore no longer yanks you back to gaming. do_restore_tv_session
now checks detect_active_session(): if a desktop session is active (the user
switched), it tears down the idle managed gamescope but does NOT restart the
gaming autologin. Observed live: the restore fired and restarted
gamescope-session-plus@ogui-steam while the client was already on the KDE
desktop.
Also: document PUNKTFUNK_SESSION_WATCH (Feature B opt-in) in the Bazzite host.env
and correct the managed-default description. Compiles, clippy/fmt clean, 78 tests.
