What is new in MountMate 5.19

### Added

- **Runtime Auto-Mount Blocking**: Blocked volumes are persisted in MountMate and rejected by Disk Arbitration while the app is running. This avoids modifying `/etc/fstab`, which is protected on recent macOS versions.
- **Startup Unmount Sweep**: When MountMate launches and finds a blocked volume already mounted because it was mounted before the app started, it unmounts it automatically, retrying briefly if the volume is still busy.
- **Keep Alive (Auto-Reconnect)**: MountMate can now keep mounts alive automatically. Network shares and volumes marked "Keep Mounted" are remounted when they drop unexpectedly, with retry attempts at a configurable interval and exponential backoff.
- **Network Change Handling**: MountMate watches the network path and remounts active shares through the new primary interface when Wi-Fi/Ethernet changes, then reconnects dropped shares as soon as connectivity recovers.
- **Mount on Login & Wake**: Keep-alive shares and volumes mount at login and reconnect promptly after the Mac wakes from sleep. Volumes unmounted by "Unmount All Disks on Sleep" come back on wake.
- **NFS & AFP Shares**: Network shares now support the NFS and AFP protocols in addition to SMB, including import of manually mounted NFS/AFP shares.
