Under rapid client reconnects, KWin's libei/EIS input setup intermittently wedged with "EIS setup timed out", causing total input loss for affected sessions. Root cause: each punktfunk/1 session opened (and tore down) its own RemoteDesktop-portal CreateSession for pointer/keyboard injection, and back-to-back reconnects raced a prior session's portal teardown before it settled. LibeiInjector is only a Send channel handle to a worker thread that owns the portal session, so the injector can live for the whole host run instead of per session. Adds InjectorService: one host-lifetime thread owns the (!Send) injector, opened ONCE (lazily, on the first event) and reused across every session — the portal grant is established a single time and held. Sessions forward pointer/keyboard events to it over a clonable Send channel; gamepads stay per-session (uinput, no portal). The service self-heals — reopen after a 2s backoff if open fails or the backend worker dies (covers a gamescope EIS socket that respawns with its nested session). Mirrors the existing host-lifetime audio-capturer slot; the audio capturer is Send (a slot works), the injector is !Send (needs the owning thread + channel). Validated live on headless KWin: 8 rapid back-to-back input sessions → "input injector ready (host-lifetime)" exactly once, ZERO "EIS setup timed out", 8/8 sessions injected input. Tests green, clippy/fmt clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
