some build and notification issues on MacOS

[solarpunkin]

1. macOS keyring crash

Bug: App crashes instantly on launch in a macOS CLI environment with ZBus Error: I/O error: Invalid argument.
This happens because oo7 defaults to the D-Bus secret service or fails to unlock the macOS Keychain when not bundled/entitled correctly.
Experienced when running cargo run or the binary directly on macOS.

2. Build Failure: blueprint-compiler missing dependencies

Bug: meson setup or compile fails because the subproject blueprint-compiler cannot find the gi python module, even if installed in python virtual environment.
The build script assumes a system-wide or perfectly linked environment that meson doesn't strictly enforce for subprojects.
Built the app from source on macOS Sequoia 15.7.4 with a Python venv. env_details.txt

3. Build Failure: missing po/LINGUAS

Bug: Meson's i18n module crashes configuration step because it expects a po/LINGUAS file to exist, but it was missing from the source tree I cloned (or the build script didn't account for it being empty/absent?)
Caught in meson setup build phase.

4. spellchecker corrections broken [intended behaviour?]

Bug: libspelling highlights words correctly, but clicking a suggestion in the context menu does nothing.
This is caused by reflection-app/src/textview.rs having a GestureClick controller that interferes with the standard right-click handling, likely deselecting the text or eating the event before the library processes it. May not be a bug rather WIP.

I can create a draft PR if you like.

Thanks for trying the app on MacOS. I have an almost working build in #164. You should be able to run the app from the build dir if you use the build script in build-aux, but the bundle doesn't work yet.

Okay I'll try this instead.
