fix: restart via systemd on linux

CHANGELOG.md

@@ -23,6 +23,7 @@
 - macOS packaging: move rpath config into swift build for reliability (#69) — thanks @petter-b
 - macOS: prioritize main bundle for device resources to prevent crash (#73) — thanks @petter-b
 - Chat UI: clear composer input immediately and allow clear while editing to prevent duplicate sends (#72) — thanks @hrdwdmrbl
+- Restart: use systemd on Linux (and report actual restart method) instead of always launchctl.
 - Docs: add manual OAuth setup for remote/headless deployments (#67) — thanks @wstock
 - Docs/agent tools: clarify that browser `wait` should be avoided by default and used only in exceptional cases.
 - Browser tools: `upload` supports auto-click refs, direct `inputRef`/`element` file inputs, and emits input/change after `setFiles` so JS-heavy sites pick up attachments.
