feat(bridge): implement presentation-aware handover and robust placeholder resolution

- Upgraded launch_from_cache to automatically trigger LibreOffice/AppleScript launchers after file copy.
- Hardened expandPath to resolve [home] and [tmp] placeholders anywhere in strings via global regex.
- Enhanced get-device-info telemetry to provide absolute home and tmp paths to the UI.
- Exposed native:launch-presentation in preload and implemented explicit LibreOffice (--impress) support on Linux.
