ComposeKey extension has stopped working

The store listing says, "This extension is no longer available because it doesn't follow best practices for Chrome extensions."

This is because it's still a Manifest v2 extension and the v3 deadline has now passed (see https://support.google.com/chrome/a/thread/325886471/migrate-extensions-to-manifest-v3-before-june-2025?hl=en).

Looks like there's work in #147 to support it, though it seems to have stalled.
