[Bug] Autocomplete / background helper still runs after OpenHuman is deleted

[Al629176]

Summary

OpenHuman inline autocomplete (or related background helper) continues running after the app is deleted/uninstalled.

Problem

• User removes OpenHuman from the machine.
• Autocomplete-related process or service still runs (e.g. notifications, hotkey listener, or helper binary).
• Causes confusion, battery use, and potential privacy concerns.

Steps to reproduce

1. Enable Text Auto-Complete / autocomplete server in OpenHuman.
2. Use autocomplete at least once.
3. Quit app and delete OpenHuman (Trash / uninstaller).
4. Observe background behavior (Activity Monitor, login items, notifications, hotkey).

Expected

All OpenHuman-related background processes stop when the app is removed (or user explicitly disables autocomplete).

Actual

Autocomplete or helper continues running after app deletion.

Tasks

• Identify which process persists (helper app, LaunchAgent, login item, separate binary).
• Ensure uninstall path removes LaunchAgents/daemons and login items registered for autocomplete.
• On app quit/disable: stop server and unregister hotkeys/listeners.
• Add cleanup on uninstall script / pkg uninstall hook (per platform).
• Document manual cleanup steps for affected users until fix ships.
• Add regression test or checklist for install → enable → uninstall → no orphan process.

Acceptance criteria

• After uninstall, no OpenHuman autocomplete process remains running.
• Disabling autocomplete stops background work immediately.
• Install/uninstall hooks documented and verified on macOS (and others if applicable).
