Adds a one-shot Hello message to the lan-mouse wire protocol so each
peer can display the other end's build commit hash and warn on
version mismatch. Soft-warn only — mismatched versions never refuse
traffic.
Wire change (lan-mouse-proto)
* `ProtoEvent::Hello { commit: [u8; 8] }` carries the 8-byte ASCII
short commit from shadow_rs's `SHORT_COMMIT`. Encoded/decoded
alongside the existing event variants.
* `EventType::Hello` is appended to the enum so existing IDs are
untouched. Old peers receive the event, hit `InvalidEventId`, and
silently skip it via the forward-compat handler in
`connect.rs::receive_loop` — the connection is unaffected.
Daemon
* Connect side sends one Hello immediately after the DTLS handshake
authenticates and before the ping_pong loop starts. Best-effort,
fire-and-forget — `log::debug!` on send error.
* Listen side mirrors the peer's Hello with its own (same shape as
the existing Ping → Pong reply), so the peer's connect-side
receive_loop populates `ClientState::peer_commit` for that
handle.
* The disconnect path clears `peer_commit` so a stale hash isn't
shown after the connection drops.
IPC
* `ClientState::peer_commit: Option<[u8; 8]>`. `None` means the
peer hasn't sent Hello yet — either fresh connection or older
build that predates the event.
GTK
* `ClientObject` exposes `peer-commit` as an `Option<String>`
property; `peer_commit_to_string` converts the wire `[u8; 8]` to
the displayable hex.
* `lan_mouse_gtk::run` now takes the local commit and stashes it in
a `OnceLock` so per-row UI can compare against each peer's hash.
* `ClientRow::refresh_version_status` re-renders the collapsed
subtitle with Pango markup whenever the property changes:
- matched → green "peer version: <hex> · matched"
- mismatch → orange "peer version: <hex> · ours: <hex>"
- unknown → orange "peer version: unknown · ours: <hex>"
* Window invokes `refresh_version_status` from
`update_client_state` after writing the new property, and
`bind` calls it once on row construction so the initial
subtitle isn't blank.
Known limitation: state-change broadcasts from the network side
(set_alive / set_active_addr / set_peer_commit) don't currently
trigger a `FrontendEvent::State` directly; the UI picks up the
latest values on the next user-driven broadcast. Same pre-existing
behavior as the alive/active_addr fields.

The previous fix created the config directory but left config.toml
absent on a first launch, which surfaced as two "No such file or
directory (os error 2)" warnings (one from the main process, one
from the spawned daemon child) and left the app starting up with
config_toml=None until the GUI persisted something.
Write ConfigToml::default() to the path if it doesn't exist, so
every entry point — GUI main, spawned daemon, CLI, test commands
— gets a concrete file to read, and first-launch logs stay clean.
Also reorders Config::new() so both the directory creation and the
file bootstrap run before the first read attempt, eliminating the
warning at the source rather than hiding it.

notify::Watcher fails on macOS if the config directory doesn't
exist. Create it with create_dir_all before calling config.watch().

* fix parsing toml key position and values
* Using rename_all instead rename over each enum
* rename struct field directly

*breaking change*
this changes the configuration syntax, allowing for an unlimited amount of configured clients.
Also a first step towards enabling a "save config" feature.
client configuration now applies immediately instead of after enabling / disabling clients.
Also fixes a potential feedback loop when changing settings.
better handling of background-service: lan-mouse can now be run without a gui by specifying --daemon as an argument.
Otherwise the servic will be run as a child process and correctly terminate when the window is closed / frontend exits.
Closes#38
major update:
- remove threading overhead by resorting to an event driven design with mio as a backend for epoll
- Clients can now have an arbitrary amount of ip adresses and lan-mouse will automatically choose the correct one
- -> seemless switching between ethernet and wifi
- cli frontend + frontend adapter for future frontends
* support for cmdline args and better error handling
* make config.toml optional
* dont abuse panic for error handling
* update doc
* more panics removed
* more unwraps removed
To reduce binary size one can now enable only specific backends, e.g.
wayland or x11 via cargo features
Additionally adds stubs for libei and xdg-desktop-portal backends
