fix(launcher): close the League client UI while a match runs
The client does not come back properly after a match when its own "Close client during game" option is enabled. The UI (LeagueClientUx and its helpers) is a Chromium/CEF instance and, under Darling, the pre-match instance keeps running: the client the backend starts when the match ends is a second CEF instance on the same --user-data-dir, and its window never paints. Its DOM and audio work and the window stays black; closing the client by hand during a match leaves the same state for the same reason. RCLOL_CLOSE_CLIENT_IN_GAME=1 opts in to closing that UI from the host, and only while a match runs, so the client that appears afterwards is the only instance. The UI also competes with the game for CPU: on a four-core host with a Radeon RX 550 a practice match reported roughly 120 FPS with the UI running and roughly 180 FPS with it closed. This is not the helper-killing memory optimization the RAM section warns against, and the Riot client, the League backend and the game are never touched. The helper fails closed. It attributes the game and the client to the launcher's prefix through the loader's __mldr_sockpath, since guest processes do not carry DPREFIX (checked on a live session). It never closes a client younger than 60 seconds (the one the backend starts after a match), preserves a process of another installation or owner, acts only when the environment and the stat fields can be read, gives up after three closes in one match, and leaves after ten minutes without a client or a match. It is off by default. Tests use fake /proc entries and mock every signal.

### Client window stays black after a match
|
||||
|
||||
The League client keeps its Chromium/CEF UI (`LeagueClientUx` and its helpers)
|
||||
alive during a match. Riot's own "Close client during game" option closes that UI
|
||||
on Windows, but under Darling the pre-match instance keeps running: the client the
|
||||
backend starts when the match ends is a second CEF instance on the same
|
||||
`--user-data-dir`, and its window never paints. Its DOM and audio work and the
|
||||
window stays black. Closing the client by hand during the match leaves the same
|
||||
state for the same reason.
|
||||
|
||||
An opt-in helper closes that UI itself, from the host, and only while a match
|
||||
runs, so the client that appears afterwards is the only instance:
|
||||
|
||||
```sh
|
||||
RCLOL_CLOSE_CLIENT_IN_GAME=1 ./scripts/run.sh
|
||||
```
|
||||
|
||||
This is not a memory measure: the UI is closed because it competes with the game
|
||||
for CPU during the match. Measured on a four-core host with a Radeon RX 550, a
|
||||
practice match reported roughly 120 FPS with the client UI running and roughly
|
||||
180 FPS with it closed. On that host a local supervisor using the same detection
|
||||
closed 13 client processes (2027 MiB resident) when a practice match started, and
|
||||
the client came back as one instance with a painted window when it ended; the
|
||||
helper described here has not been through a live match yet. Riot's own option is
|
||||
the equivalent on Windows, so leave either one disabled if the in-client chat is
|
||||
wanted during a match.
|
||||
|
||||
The helper is off by default and fails closed: it attributes both the game and the
|
||||
client to the launcher's prefix through the loader's `__mldr_sockpath` (guest
|
||||
processes do not carry `DPREFIX`), never closes a client younger than 60 seconds
|
||||
(the one the backend starts after a match), leaves the Riot client, the League
|
||||
backend and the game untouched, and takes no action when ownership, the
|
||||
environment or the stat fields cannot be read. The client UI is recognised by the
|
||||
name of its executable, not by the command line: `LeagueCrashHandler` processes
|
||||
carry the client UI name in their arguments only, so they are left alone. It
|
||||
leaves by itself after ten minutes without a client or a match. Diagnose it in one

Opt-in helper for `run-riot-client.sh` (`RCLOL_CLOSE_CLIENT_IN_GAME=1`). The

League client keeps its Chromium/CEF UI (executable `LeagueClientUx` and its

and the client the backend starts when the match ends is a second CEF instance
