KeyFinder is now available on both browsers.

• Firefox: Download keyfinder-v2.0.0-firefox.zip, load via about:debugging > "This Firefox" > "Load Temporary Add-on"

What changed

• Added manifest.firefox.json with gecko-specific settings (background.scripts instead of service_worker)
• Added data_collection_permissions for AMO compliance
• Added scripts/build.sh for packaging both browser versions
• Zero JavaScript changes - Firefox 128+ supports chrome.* namespace and world: "MAIN" natively

Closes #10.
