Per plan §2.5: the security-critical rustls fingerprint-pinning ServerCertVerifier
was hand-rolled three times — quic/endpoint.rs (PinVerify), pf-client-core
library.rs, punktfunk-tray status.rs — drifting copies on a trust boundary. Add
one canonical punktfunk_core::tls::PinVerify (+ cert_fingerprint) behind a light
`tls` feature (rustls + sha2 only, no QUIC runtime); `quic` now depends on it, and
quic::endpoint re-exports cert_fingerprint so that path stays byte-stable
(gamestream + pf-client-core reach it there).
- core::tls::PinVerify: new(pin) for the HTTP clients, with_observed(pin, slot)
for the QUIC TOFU connect. Behavior-identical to all three originals (pin-check
+ real CertificateVerify signature verification; only hashes the leaf when a pin
or observed slot needs it). Two focused unit tests anchor the boundary.
- quic/endpoint.rs: drop the private PinVerify, wire client_pinned through
tls::PinVerify::with_observed.
- pf-client-core library.rs + tray status.rs: use the shared verifier; tray also
routes load_pin through core cert_fingerprint and drops its direct sha2 dep,
gaining only the light core `tls` feature (still no host dep, no QUIC runtime).
Verified on Linux (home-worker-5): clippy 0/0 for core(quic), core(tls),
pf-client-core, tray, host(nvenc,vulkan-encode,pyrowave); core 153 lib tests +
loopback 7/7 (pinned handshake) + c_abi round-trip green.

Session pump, FFmpeg decode, PipeWire audio, SDL3 gamepads, keymap, trust
store, mDNS discovery, library client and Wake-on-LAN move verbatim from
clients/linux into crates/pf-client-core, shared with the upcoming Vulkan
session binary (punktfunk-planning: linux-client-rearchitecture.md).
The GTK client re-exports them at the crate root so every existing
crate::-path keeps resolving; its manifest drops the moved-only deps.

New crates/punktfunk-tray — a small per-user companion showing the host service
state at a glance (running / stopped / starting / degraded / failed + the live
session in the tooltip) with one-click actions: open web console, approve a
pending pairing request, start/stop/restart, open logs. No more digging through
logs to learn whether the service came back after a reboot or an update.
Status is service-manager-FIRST (SCM / systemd user unit — a port squatter can
never fake Running), then the new loopback-only unauthenticated
GET /api/v1/local/summary (counts/booleans only; the mgmt token and cert.pem
are SYSTEM/Admins-DACL'd on Windows, so a non-elevated tray cannot bearer-auth).
Windows: windows_subsystem binary (a console exe in the Run key would flash a
terminal at sign-in), Shell_NotifyIcon + hidden window, per-session single
instance, TaskbarCreated re-add, --quit for the uninstaller; service actions
elevate per click via ShellExecuteW "runas" onto the new
`punktfunk-host service restart` (stop → wait Stopped → start).
Linux: ksni/StatusNotifierItem over zbus, systemctl --user actions (no polkit),
/etc/xdg/autostart entry whose --autostart self-gates to actual host users.
Icons: scripts/gen-tray-icons.py (pure stdlib) renders the brand lens + status
dot into committed .ico/hicolor assets; deb/rpm/arch ship binary+autostart+icons.
Live-validated: Linux on the headless KDE session (SNI registration, state
transitions, menu-driven start, dbusmenu layout); Windows on the RTX box
(session-1 launch with no NIM_ADD failure, single instance, --quit, restart
round-trip, summary loopback-200/LAN-401).
