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.

+# eval-cli
+
+Headless CLI binary for running Zed's agent in evaluation/benchmark
+environments. Designed to work inside containerized environments like
+[Harbor](https://harborframework.com/) where the repository is already
+checked out and API keys are provided via environment variables.
+
+Uses the same `NativeAgent` + `AcpThread` pipeline as the production Zed
+editor — full agentic loop with tool calls, subagents, and retries, just
+without a GUI.
+
+## Building
+
+### Native (for local testing on the same OS)
+
+```
+cargo build --release -p eval_cli
+```
+
+### Cross-compile for Linux x86_64 (from macOS or other hosts)
+
+Harbor containers run Linux x86_64. Use the Docker-based build script:
+
+```
+crates/eval_cli/script/build-linux
+```
+
+This produces `target/eval-cli` (an x86_64 Linux ELF binary). You can
+also specify a custom output path:
+
+```
+crates/eval_cli/script/build-linux --output ~/bin/eval-cli-linux
+```
+
+## Standalone usage
+
+```
+eval-cli \
+  --workdir /testbed \
+  --model anthropic/claude-sonnet-4-6-latest \
+  --instruction "Fix the bug described in..." \
+  --timeout 600 \
+  --output-dir /logs/agent
+```
+
+Reads API keys from environment variables (`ANTHROPIC_API_KEY`,
+`OPENAI_API_KEY`, etc.). Writes `result.json`, `thread.md`, and
+`thread.json` to the output directory.
+
+### Exit codes
+
+| Code | Meaning                            |
+| ---- | ---------------------------------- |
+| 0    | Agent finished                     |
+| 1    | Error (model/auth/runtime failure) |
+| 2    | Timeout                            |
+| 3    | Interrupted (SIGTERM/SIGINT)       |
+
+## Harbor integration
+
+The `zed_eval/` directory contains a Python package that
+implements Harbor's `BaseInstalledAgent` interface, allowing eval-cli to
+be used with `--agent-import-path` without modifying Harbor's source code.
+
+### Setup
+
+```
+pip install -e crates/eval_cli/harbor/
+```
+
+### Running with a local binary
+
+Build for Linux first, then pass the binary path:
+
+```
+crates/eval_cli/script/build-linux
+
+harbor run -d "swebench_verified@latest" \
+  --agent-import-path zed_eval.agent:ZedAgent \
+  --ae binary_path=target/eval-cli \
+  -m anthropic/claude-sonnet-4-6-latest
+```
+
+The agent uploads the binary into the container during setup — no
+download URL needed during local iteration.
+
+### Running with a download URL
+
+For CI or when the binary is hosted somewhere:
+
+```
+harbor run -d "swebench_verified@latest" \
+  --agent-import-path zed_eval.agent:ZedAgent \
+  --ak download_url=https://example.com/eval-cli \
+  -m anthropic/claude-sonnet-4-6-latest
+```
+
+### Setting a timeout
+
+Pass `EVAL_CLI_TIMEOUT` via `--ae`:
+
+```
+harbor run -d "swebench_verified@latest" \
+  --agent-import-path zed_eval.agent:ZedAgent \
+  --ak binary_path=target/eval-cli \
+  --ae EVAL_CLI_TIMEOUT=600 \
+  -m anthropic/claude-sonnet-4-6-latest
+```
