Adds an SSHClient gomobile binding so the Android app can run an SSH session over the tunnel with a PTY, exposed through a listener interface for the in-app terminal.
Server type is auto-detected from the SSH banner, which selects the auth path: JWT device-code flow, NetBird key, or a regular server (NetBird key first, then password). Host keys are verified against the peer registry for NetBird servers and trust-on-first-use for regular ones.
## Describe your changes
Validate peer-supplied FQDN and hostname before they are written into
the
generated NetBird SSH client config (`client/ssh/config/manager.go`).
These
values originate from remote peers and were previously written verbatim
into
the config; malformed values (e.g. containing unexpected characters)
could
produce a broken or unintended config. FQDN/hostname are now checked
with
`domain.IsValidDomainNoWildcard`, and invalid, non-empty values are
dropped
with a warning. IPs are unaffected (already validated `netip.Addr`).
Added a
test covering malformed hostnames.
## Issue ticket number and link

N/A
- **Wails v3 application** (`client/ui`) with a React + TypeScript + Tailwind frontend replacing the Fyne UI: main connection view, exit-node switcher, networks/peers browser with detail panels, profile management, settings (general, network, SSH, security, troubleshooting, appearance), debug-bundle creation, and a first-run welcome flow.
- **Internationalization**: go-i18n bundle with 9 locales (en, de, es, fr, hu, it, pt, ru, zh-CN) shared between the tray and the frontend.
- **New system tray** implementation with per-platform theme-aware icons, including a native XEmbed host for Linux (`xembed_tray_linux.c`) and a Linux theme watcher.
- **Session handling**: auth session watcher (`client/internal/auth/sessionwatch`), pending login flow, session-expiration dialog and tray notifications, and `netbird login` improvements.
- **Daemon API extensions** (`daemon.proto`): status stream subscription, event stream, networks/exit-node selection endpoints, and richer full status — with probe throttling on the daemon side to protect against UI-driven request storms.
- **UI preferences store** persisted per profile, autostart management via the daemon (single source of truth in HKCU on Windows).
- **Build system**: Taskfile-based builds per platform (macOS, Linux, Windows), Docker cross-compilation images, MSIX/NSIS/nfpm/AppImage packaging, and a new `frontend-ui` CI workflow.

* [client] categorize root/system-mutating tests behind a privileged build tag
Tests that need root or mutate host state (nftables/iptables/DNS, TUN/WireGuard
interfaces, routes, eBPF, SSH/service install) are now gated behind a
//go:build privileged tag. The default `go test ./client/...` runs as a non-root
user with no sudo and leaves host networking untouched; mixed files were split so
pure-logic tests stay in the default suite.
A self-hosting ory/dockertest/v4 harness (client/testutil/privileged) runs the
privileged suite inside a --privileged --cap-add=NET_ADMIN container via
`make test-privileged`; a DOCKER_CI=true guard skips the spawn when already inside
the container. Added `make test-unit` for the host-safe run.
* [client] add PRIV_RUN/PRIV_PKGS filters to the privileged test harness
The dockertest harness now reads two optional env vars when building the
in-container `go test` command: PRIV_RUN adds a -run test-name filter and
PRIV_PKGS overrides the package list. Both empty reproduce the full privileged
suite, so CI and `make test-privileged` behave as before. Lets a developer run a
single privileged test in the container, e.g.:
PRIV_RUN=TestNftablesManager PRIV_PKGS=./client/firewall/nftables/... make test-privileged
* [client] fix unused-helper lint after the privileged test split
Splitting privileged tests into *_privileged_test.go left their shared helpers in
the untagged files, so in the default (no-tag) build they had no callers and
golangci-lint flagged them as unused.
Moved the privileged-only helpers into the privileged files next to their callers
(generateDummyHandler; createEngine/startSignal/startManagement/getConnectedPeers/
getPeers + kaep/kasp; (*mockDaemon).setJWTToken). Annotated the shared routing-test
fixtures that must stay untagged for cross-platform compilation with //nolint:unused
(systemops_bsd expected* vars, ensureIPv6DefaultRoute on bsd/windows,
loopbackIfaceWindows), matching the existing linux variant.
* [client] fix privileged test CI failures and run the harness on macOS
The host-safe unit run dropped sudo but two privileged test groups were
never tagged, and the Docker privileged job silently never ran the suite:
- Gate the ssh/server PrivilegeDropper command-construction tests behind
the privileged tag (they require root to target a different UID); split
them into executor_unix_privileged_test.go.
- Tag sharedsock raw-socket tests privileged (need CAP_NET_RAW).
- Fix the Docker job command: nested single quotes around the build tags
closed the sh -c wrapper early, dropping the go list package set and the
privileged tag, so go test ran on the empty repo root. Use double quotes.
Make the self-hosting harness usable from a dev Mac:
- Build it on darwin as well as linux; it only drives Docker.
- Resolve the active docker context endpoint into DOCKER_HOST when the
default /var/run/docker.sock is absent (Docker Desktop, Colima, OrbStack).
- Rename the misspelled containerGoModache constant to containerGoModCache.

* [ci] Run privileged-tagged tests on darwin, windows and freebsd
The privileged build tag split moved root/system-mutating tests behind
//go:build privileged, but only the linux docker job was given the tag.
The native darwin (sudo), windows (PsExec64 -s) and freebsd VM runners
already have the required privileges, so add the privileged tag there too
to keep CI running the same set of tests as before the split.
* [ci] Exclude dockertest harness from the darwin privileged run
The privileged tag now compiles client/testutil/privileged on darwin, whose
TestRunPrivilegedSuiteInDocker spawns a container the macOS runner has no
Docker for. Exclude the harness package from the darwin list, matching the
linux job, so the privileged tests run in place without a container spawn.

Increase DefaultJWTMaxTokenAge from 5 to 10 minutes to accommodate
identity providers like Azure Entra ID that backdate the iat claim
by up to 5 minutes, causing tokens to be immediately rejected.

- Automatic Unix daemon address discovery: if the default socket is missing, the client can find and use a single available socket.
- Client startup now resolves daemon addresses more robustly while preserving non-Unix behavior.
* **New Features**
* SSH server JWT validation now accepts multiple audiences with backward-compatible handling of the previous single-audience setting and a guard ensuring at least one audience is configured.
* **Tests**
* Test suites updated and new tests added to cover multiple-audience scenarios and compatibility with existing behavior.
* **Other**
* Startup logging enhanced to report configured audiences for JWT auth.
