* Extract the Wi-Fi QR share card into its own omarchy.wifiqr panel plugin omarchy-network-qr now leads with an iface/security/ssid meta line, so a bare summon self-detects the connection and the plugin owns the whole share flow. The network panel loses its overlay lifecycle: with no centered card left inside it, the shadowed open/close collapses back to the stock panel behavior, and the QR button just summons the plugin -- which a clone or third-party plugin can replace, like the speed test. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Keep canceled QR and password runs from leaking into their replacements Copilot review: the cancellation guards dropped in onExited while the canceled run's collectors were still allowed to fire, so a stale stderr could shadow a successful regeneration and a stale password could be revealed under a new network's card. The guards now stay up until the next run launches, good output settles any earlier error, and a bare re-summon no longer inherits the previous card's SSID.
