### System details

- Omarchy 4.0.4-1
- Hyprland 0.56.2 (package 0.56.2-2), Lua configuration
- hyprmoncfg-bin 1.22.0-1; daemon restarted into 1.22.0 before the final reproduction
- Kernel 7.2.5-3-omarchy
- ThinkPad T14s Gen 1, Intel Core i5-10210U / Intel UHD Graphics (i915)
- Internal eDP-1: 1920×1080, scale 1.5
- External HP 727pu on DP-2 over direct USB-C: 2560×1440, scale 1

### What's wrong?

With hyprmoncfg managing the display configuration, the built-in Quickshell menu action **Trigger → Hardware → Mirror Display** reports that mirroring is enabled, but the desktop remains extended. This appears to be an integration conflict between Omarchy's toggle configuration and hyprmoncfg's generated layout.

The monitor is connected and functioning normally in extended mode. This report concerns mode switching, not USB-C detection.

### Steps to reproduce

1. Run Omarchy with an internal and external display in extended mode.
2. Enable hyprmoncfg management and run `hyprmoncfgd`.
3. Use the built-in **Mirror Display** menu action. Its stock command is `omarchy-hyprland-monitor-internal-mirror toggle`.
4. Inspect `hyprctl -j monitors all`: the external display still has `mirrorOf: "none"`.

I also reproduced this directly with the unmodified packaged command, bypassing a local menu workaround:

```sh
/usr/share/omarchy/bin/omarchy-hyprland-monitor-internal-mirror on
hyprctl -j monitors all | jq '[.[] | {name, mirrorOf, x, y}]'
```

Result:

```json
[
  {"name":"eDP-1","mirrorOf":"none","x":0,"y":0},
  {"name":"DP-2","mirrorOf":"none","x":1280,"y":-360}
]
```

The toggle file exists and contains:

```lua
hl.monitor({ output = "DP-2", mode = "preferred", position = "auto", scale = 1, mirror = "eDP-1" })
```

`hyprctl configerrors` is empty.

### Expected behavior

The menu action should switch the external display to mirroring and toggle back to the previous extended layout, including when hyprmoncfg manages displays. If that combination is unsupported, the command should report the conflict rather than report success.

### Configuration conflict

The user configuration loads `require("default.hypr.toggles")` before hyprmoncfg's managed `dofile(...)` include. hyprmoncfg deliberately puts its generated monitor configuration last. That generated configuration contains the extended layout without a mirror setting, overriding the earlier toggle rule. The daemon can also restore its selected layout after an external change.

The current upstream [mirror command](https://github.com/omacom/omarchy/blob/c05d90196fc0dd5c21e2e797d80ffcc60d5e39fa/bin/omarchy-hyprland-monitor-internal-mirror) writes the toggle and reloads Hyprland without coordinating with the active display manager or verifying the resulting mirror state.

### Working local integration / validation

A user-level menu override now delegates switching to hyprmoncfg: save the extended layout, create a mirror profile using the internal output's **hardware key** as `mirror_of`, and apply the appropriate profile through the daemon. The daemon remains enabled.

I tested **extended → mirrored → extended through the actual Quickshell menu route**, verifying the resulting `mirrorOf` values and empty configuration errors. Both directions work through that integration. No packaged Omarchy files were changed.
