Replaces the synchronous, blocking file-read loop in the `load_extensions`

startup when loading multiple user scripts, significantly improving performance
for users with many extensions.

Signed by a new key (public half embedded in tauri.conf.json, private
half + password live in GitHub secrets). CI now signs release artifacts
and publishes latest.json; the app checks on boot and prompts to
install and restart.
