Initial commit: Rust notification badge daemon for KDE Plasma 6

Monitors D-Bus for desktop notifications and emits Unity LauncherEntry
badge updates so KDE Plasma task manager shows notification counts.

- Streaming dbus-monitor parser with app matching and lifecycle tracking
- KWin window discovery for automatic desktop file detection
- Systemd user service, Makefile install/uninstall targets
- 38 tests (32 unit + 6 integration), 97% line coverage via cargo-llvm-cov
- CodeScene code health: 10/10 on all source files
