DigitGlance Desktop v1.0.1

chore: bump version to 1.0.1 (ship the official blue logo) (#3)

The published v1.0.0 installers were built before the blue-monogram icon
fix, so the live download + installed apps still show the old teal mark.
Bump the version across tauri.conf.json, package.json and Cargo.toml so a
fresh `v1.0.1` release rebuilds the installers with the correct icon and
auto-updates existing installs.

To ship: merge this, then push tag `v1.0.1` (the release workflow rebuilds
Windows + macOS, regenerates icons from assets/icon-source.png, and drafts
a signed release + updater feed to publish).
