Feature: ignore-focus-from config to prevent focus-stealing apps

[noomzopendream]

Problem

Some background apps/services steal focus when they activate, disrupting workflow. For example, Logitech's LogiPluginService activates when plugging/unplugging devices, causing AeroSpace to switch workspaces unexpectedly.

Proposed Solution

New config option ignore-focus-from that accepts an array of app bundle IDs to ignore focus events from:

ignore-focus-from = ['com.logi.pluginservice']

Implementation

I've implemented this in my fork: https://github.com/noomz/AeroSpace/tree/ignore-focus-from

• Filters focus events in GlobalObserver.onNotif() before any downstream processing
• Uses Set<String> for O(1) lookup (called on every focus event)
• Config check happens inside @MainActor Task block to safely access config

Use Cases

• Logitech software (com.logi.pluginservice) - activates on device connect/disconnect
• Other background utilities that occasionally steal focus
• System services that shouldn't trigger workspace switches

Looking for feedback on this approach.
