v0.15.0

### Added
- **Ubuntu PPA Packaging**: Official Ubuntu PPA repository for easy installation on Ubuntu/Debian-based distributions
  - Automated GitHub Actions workflow for PPA releases
  - Support for multiple Ubuntu versions

### Changed
- **Bandwidth Sorting**: Changed bandwidth sorting to use combined up+down total instead of separate up/down sorting
  - Simpler sorting behavior: press `s` once to sort by total bandwidth
  - Display still shows "Down/Up" with individual values
  - Arrow indicator shows when sorting by combined bandwidth total
- **Packet Capture Permissions**: Removed CAP_NET_ADMIN and CAP_SYS_ADMIN requirements
  - Uses read-only packet capture (non-promiscuous mode)
  - Reduced security footprint with minimal required capabilities

### Fixed
- **Bandwidth Rate Tracking**: Improved accuracy and stability of bandwidth rate calculations
  - More consistent rate measurements
  - Better handling of network traffic bursts
