rename: lumen → punktfunk, everywhere
ci / rust (push) Has been cancelled

Full project rename, decided 2026-06-10:
- Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs.
- C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h,
  PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl.
  PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants).
- Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1.
  WIRE BREAK: clients must be rebuilt from this revision.
- Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / ….
- Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the
  persistent identity is unchanged, pinned fingerprints stay valid).
- Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection
  (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated.
- scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated.

Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of
"desktop but no apps/settings" over the stream: plasmashell launched without
XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and
rendered an empty menu. The script sets the complete KDE session env (menu prefix,
KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell.

Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS,
zero lumen references left outside .git.

//! Input injection (plan §4): turn client [`punktfunk_core::input::InputEvent`]s into host input.
//!
//! The headless Sway compositor runs with `WLR_LIBINPUT_NO_DEVICES=1`, so kernel `uinput`
//! devices are never picked up. Instead we inject through the wlroots virtual-input Wayland
//! protocols — `zwlr_virtual_pointer_manager_v1` + `zwp_virtual_keyboard_manager_v1` — which
//! Sway always advertises. We connect as an ordinary Wayland client (the host process
//! inherits Sway's `WAYLAND_DISPLAY`/`XDG_RUNTIME_DIR`), bind the two managers, and translate
//! events into virtual pointer/keyboard requests. Keyboard codes are Linux evdev; we upload a
//! standard evdev/US xkb keymap and track modifier state so the compositor resolves shifted
//! keysyms correctly.
