Implementation of Safari Web Extension and communication with KeePassXC.

[sebastianlivoni]

With continuation of work from pull request #1035 and issue #294, I've added the ability for KeePassXC to communicate with the Safari Web Extension. Messages are sent from KeePassXC to the Web Extension and vice versa.

The solution requires that KeePassXC saves the socket to ~/Library/Group Containers/G2S7P7J672.org.keepassxc.KeePassXC/KeePassXC.BrowserServer and adds the app group entitlement for G2S7P7J672.org.keepassxc.KeePassXC.

Changes:

• Merges the latest develop changes.
• UI for enabled/disabling Safari extension.
• Added hardened runtime entitlement required for App Store.
• Minor changes to existing web extension code such as adding correct classNames for Safari.
• The returningItems parameter in context.completeRequest was removed, and SFSafariApplication.dispatchMessage is now used instead.

The app MUST be distributed through the macOS App Store requiring a Apple Developer Account (99 USD each year).

Testing strategy

I've made visual testing checking whether images are correctly loaded for Safari Web Extension and tried to use the extension on multiple websites including autofilling and lock / unlock of database.

In order to test this, make sure to use a build of KeePassXC that saves the socket to ~/Library/Group Containers/G2S7P7J672.org.keepassxc.KeePassXC/KeePassXC.BrowserServer

Type of change

• ✅ New feature (change that adds functionality)

Maybe the App Icon should be similar to 1Password for Safari (I'm talking about the puzzle piece) to indicate an extension.

I think it is ready for some testing.

Uh oh was that an accident?

Yes that was an accident... I wanted to delete some other local branches...

I'll review this soon. Sorry for the delay!

[sebastianlivoni]

With the new macOS 15.4 update, it looks like it is possible distribute the Safari Web Extension within the KeePassXC app itself making a separate release on App Store unnecessary. I will be looking into this and make changes in the other repository.
