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.

//! Management REST API (plan §4) — the control-plane surface a control pane / CLI talks
//! to: host identity + capabilities, runtime status, paired-client management, the pairing
//! PIN flow, and session control. Control plane only — `tokio`/`axum` are permitted here;
//! the per-frame pipeline never touches this module.
//!
//! The API is versioned under `/api/v1` and described by an OpenAPI 3.1 document generated
//! at compile time with `utoipa` — `punktfunk-host openapi` prints it for client codegen, the
//! running server serves it at `/api/v1/openapi.json` plus interactive docs at `/api/docs`,
//! and a copy is checked in at `docs/api/openapi.json` (a test fails if it drifts, like the
//! cbindgen header).
//!
//! Security: binds loopback by default. A bearer token (`--mgmt-token` / `PUNKTFUNK_MGMT_TOKEN`)
//! is enforced on every `/api/v1` route except `/api/v1/health`, and is mandatory for
//! non-loopback binds. The OpenAPI document and docs UI are served unauthenticated (the
//! spec is public knowledge — it lives in this repo).
