logiguard fork: GPUI xdg-activation keyboard-focus serial fix

Single-commit orphan branch: full zed-industries/zed @ 8c74db0 source tree
with a 3-file patch applied (no upstream history).

Patch (crates/gpui_linux/src/linux/wayland/):
  - serial.rs: add SerialKind::KeyboardEnter
  - client.rs: store wl_keyboard.enter serial; add latest_serial_of()
  - window.rs: activate() uses keyboard-enter serial (Mutter focus gate)

Mutter honors window activation only when the token carries the keyboard-
focus serial from wl_keyboard.enter; GPUI used a stale mouse-press serial.
See docs/tray-window-focus-wayland.md in logiguard.

+# This config is different from config.toml in this directory, as the latter is recognized by Cargo.
+# This file is placed in ./../.cargo/config.toml on CI runs. Cargo then merges Zeds .cargo/config.toml with ./../.cargo/config.toml
+# with preference for settings from Zeds config.toml.
+# TL;DR: If a value is set in both ci-config.toml and config.toml, config.toml value takes precedence.
+# Arrays are merged together though. See: https://doc.rust-lang.org/cargo/reference/config.html#hierarchical-structure
+# The intent for this file is to configure CI build process with a divergance from Zed developers experience; for example, in this config file
+# we use `-D warnings` for rustflags (which makes compilation fail in presence of warnings during build process). Placing that in developers `config.toml`
+# would be inconvenient.
+# The reason for not using the RUSTFLAGS environment variable is that doing so would override all the settings in the config.toml file, even if the contents of the latter are completely nonsensical. See: https://github.com/rust-lang/cargo/issues/5376
