feat(menu): show current version on the Check-for-Updates entry

Appends ' · v{CARGO_PKG_VERSION}' to every state of the version-action
menu item so users can see what they are running without opening an
About dialog. Reads as 'Check for updates · v0.1.7', 'Up to date ·
v0.1.7', etc. Winget channel decoration is preserved as a trailing
parenthetical.

Bumps version to 0.1.7.
