Incompatibility with AGS 3.0.0

[mixchar41]

Describe the bug
HyprPanel cannot presently be built because current Astal doesn't seem to create a GJS package anywhere, let alone /usr/share/astal/. Expecting this package to be present, any attempt to build HyprPanel will be prevented.

Running npm i inside the directory yields this error:

npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /usr/share/astal/gjs/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/usr/share/astal/gjs/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent 

npm ERR! A complete log of this run can be found in:
npm ERR!     /home/mxch/.npm/_logs/2025-11-15T20_50_03_092Z-debug-0.log

Without successfully performing the NPM installation, running meson setup build returns a successful setup, but running meson compile -C build following that instead produces a lengthy series of errors for every time the code attempts to import Astal. Most assume this format:

✘ [ERROR] Could not resolve "astal"

    src/components/settings/shared/Label.tsx:1:35:
      1 │ import { Binding, execAsync } from 'astal';
        ╵                                    ~~~~~~~

  You can mark the path "astal" as external to exclude it from the bundle, which will remove this error and leave the unresolved path in the bundle.

To Reproduce

• use (hypothetically) any OS without up-to-date Hyprland packages
• manually build latest GitHub versions of Astal IO, GTK3, GTK4 and AGS according to manual instructions (!! and set the meson installation directory to /usr !!)
• perform step 3 of HyprPanel installation (npm i in directory), or
• perform steps 4 and 5 of HyprPanel installation (meson setup build; meson compile -C build)

Expected behavior
successful NPM installation; subsequent meson build

Desktop

• Distribution: Debian
• Window Manager: Hyprland
• AGS version: 3.0.0
• Astal version: 0.1.0

Involuntarily, the title is misleading, as AGS is not the issue here, as I've further discovered.
