Module update 

Functions

current_version

Current compiled-in version from Cargo.toml.

self_update

Self-update the purple binary to the latest release.

spawn_version_check

Spawn a background thread to check for updates. Sends an event if a newer version exists. Uses a local cache (~/.purple/last_version_check) with a 1h TTL to avoid unnecessary GitHub API calls on frequent startup. Silently does nothing on any error.

update_hint

Detect the update command appropriate for how purple was installed.
